Ok guys so my car has almsot 2K miles on the new engine. Can i start red lining her yet? I know i should take it easy up to i think i read 3K but i want to red line god dam it!!! :P

KimRene

PS = I put in 5W20/30 conventional oil for break in already 3 weeks ago.

Don't know how I missed this thread 'til now Kim, especially from a fellow taxachusetian, but great to see it's all sorted out for you. 2k miles is more than enough break in. Get your oil changed, to remove the break-in metal shavings contaminants, and have fun in the finally-Spring weather!

KimRene

Thanks James.... i did this morning as a matter of fact on my way to work on the highway... LOL
I will continue to do this once a day like i should.

Huey i just got an oil change not to long ago so i am waiting for another 1K miles to get it done. Then i will do the normal every 3K miles on it but i am switching my oil to 10W30. No more 5W20!

KimRene

No I am not experiencing that anymore however..... this morning when i was trying to red line in 2nd gear in my AT it kind of hesitated and the check engine light came on flickering on and off then it stayed on and now its on! WTF???? So i called up the dealership and i work like a frigin dog so the next time i can drop it off is this coming Tuesday morning. So i am not going to red line this thing anymore cuz i dont know if it would damage the engine or whatever is wrong with it? I dont get it????

Any ideas on what may have caused this????

KimRene

I dont think its the spark plugs cuz the dealership replaced some close to 2 months ago and the coils i got done around 20K miles ago. Dealership also did new wiring in my car as well.... however though, yesterday i was reading a thread then i got busy again at work so i couldnt read the whole thing but it was a thread under Trouble Shooting that was talking about the issue that i think i may have but it was mostly happening to 04 & 05 MT not AT like i drive.... The car is hesitating to red line period and it gets stuck between 6-6.5 RPM. I am going to see if i can find that thread again and see what they diagnosed it with....

I will private message you my cell # in case we can meet up this weekend but i do have a wedding shower this Saturday that i am throwing so i will be pretty much booked on that day and i am missing an RX-8 Spring Clean Meet too! .... i will try to get to autozone sometime this weekend to get a read and i will post it up here in case we dont meet.

Thanks again for your help and advice!

KimRene

All, i didnt have time to go to the Autozone to get a free read but i knew that my engine is under warranty and i brought my car to get the read..... this is what i was told..... DO NOT RED LINE.... I am sooooooooo confused!?!?!?!?!?!?!? It was a misfire like you said Joe. I have attached the full report and they also gave me a copy of the actual readings that i also attached. They told me that i should NOT BE REDLINING my vehicle and i told them that they dont know crap about their cars and that the point of redlining once a day was to remove carbon buildup and it was supposed to be better for your engine in the long run. They told me again.... DO NOT REDLINE. And told me that the new engine in my car is preventing me from redlining..... they stop at 6-6.5 RPM automatically....

So i was like i have to call up MNAO to verify this **** and when i did the customer service guy told me DO NOT RED LINE as well. No i am so f'n confused?!?!?!?!? He also emailed me little guide on how to drive my car.... i will attach that as well.

KimRene

What are your thoughts guys???? This ought to be good..... lol

I laughed a little. There is nothing in the software or mechanically unless mechanically screwed up that I'm aware of which should stop you from revving it as high as it will go. That being said, if it doesn't go past 6-6.5 rpm which isn't even the 4-port redline I'd be suspicious to them lowering your rev limiter which I find hard to believe where you can't even get to redline.

As for damaging the car, constant redline may do that over a period of time but revving up to the redline will not. Even the dealer before I got into all the technical side of the car on the forum here suggested the redline once a day.

RIWWP

From the driver's guide they sent you:
So nothing there about not redlining it.

I mean, the engine is limited....by a fuel cut-off at redline. If you literally can't rev over 6 or 6.5rpm, then something is wrong, describe what it is you feel when it cuts off. Otherwise your redline is correctly limited at 7,500.

Tech + MNAO don't know the car and don't know what they are talking about.

For crying out loud, if the engine wasn't supposed to rev over 6,500 rpm, then that is where the redline would be. On piston engines, high revs aren't healthy, even below redline, but not inherently damaging. Rotaries are different, but the redline is the redline because THAT is the point that you aren't supposed to go over.

Not some nebulous number below redline.

Tell that to MM when he pushed the last car at Dyno days past 10k

RIWWP

iTrader: (2)

Yup. Even the jacked up incompetent dealer that showed horrifically failing compression numbers pulled the same freeze frame data on my misfire code, the techs were laughing when they said "at least you drive the car the way you are supposed to. The misfire was at 8,400 rpm" (or something like that) "too many people just lug it around in low RPM all day."


Kim,

If you are getting high end misfires, likely you have a coil, a plug wire, or a plug that is going bad. Start with an e-shaft sensor reset (20 brake pedal stomp method), then to the oldest components first, but there are very very few other reasons. O2 sensor could be a cause, engine compression failing could be a cause....and that's about it. Since you have a new engine, compression is not something to worry about. O2 sensor only if the rest aren't the issue.

My needle has hit 10k before.


My needle is also probably off.








And yes, that's what she said.

KimRene

I just checked my email becuase i forgot to mention that the Rep from MNAO told me that he would email me back and look more into the redlining thing.... and this is what i got.....

Hi Ms. Rene,
Thanks for your patience. We recommend you drive the vehicle within the operating range but an occasional trip toward the redline may help prevent excessive carbon build up. In essence, you don't need a daily visit to the redline. I hope this helps.

Sincerely,
Mazda Customer Assistance

Dealership before i went to this one told me that too to redline once a day.... maybe i have to break in my engine more? i dont want to have problems red lining and my check engine light coming on every time ya know?

Vlaze

If the engine is new, break in is a good way to go about it. I wouldn't redline it for a few hundred miles for a new engine break in then progress my way up to it.

RIWWP

iTrader: (2)

He had to research it.

Kim, you almost certainly have a bad coil, plug or wire if it is that consistent. Probably a wire from my guess. Coils and plugs seem to cause misfires more randomly. You might have gotten a cut or something in the wire shielding. It's not all that far from the wheel well and road debris. Entirely possible.

Plus they did reuse your old stuff that was on the engine before replacement, so, it could have been bad since then.

RIWWP

iTrader: (2)

She has 2k+ on the new engine. Break in is done, i seriously doubt this is related.

Vlaze

iTrader: (14)

I didn't say it was related, just stating in general for break in.

2k is enough indeed, I agree if they used parts off the previous engines they can easily be a culprit.

But the engine only allowing her to get up to 6-6.5k? I'm failing how to see plugs/coils, etc preventing that. Seems something else is in play here.

KimRene

Alright Mike, i will try to find someone who can look into it and this time i am going to pay very close attention so that i can learn how to check my own car for coils, plugs, and other little things that like that.

I also agree with you that something is still wrong with my car cuz before you witnessed in my car last spring when we installed those coils that my car was redlining fine when we took it for a test ride. My car was redlining fine before so i know that something small is wrong with it.... Yeah i read what they said about AT engines redlining at 7.5RPM and MT at 9K rpm.... but you have to understand that i have had the worst luck with this car and i dont want to **** it up becuase i do love this car too. Even after all the aggrivation she put me through, i still love her.... LOL.

So basically that was why and why i am scared to redline it.... so until i get someone to look at it, i will rev up my engine close to it in 2nd gear on the highway. Best as i can do for now without getting a check engine light on again... plus i need to get my car inspected by the end of this month.... LOL

Any chance you are around / free this Friday afternoon/evening? I am headed to Chicago for the next 2 days, then Friday I am back before heading down to VA on Sat, back on Monday. I'd be happy to take a look, show you a few things, like how to check the wires, coils, plugs, etc...

These links may help you with a little more info on the rev limiter story line Kim - maybe put your fears slightly more in the backseat as you get closer to that redline. Just a passing comment on the replaced engine too - did the dealer do any compression tests on the replacement motor when they installed it? It is rare, but folks have gotten bad remanufactured motors from the facility Mazda works with here in the US to do rotary rebuilds that they then ship off to dealers as replacements. If all else fails, this might be your last option to investigate.

Actually yesterday, as i was driving into work.... i went onto an onramp and passing a darn Walmart 18 wheeler and i was in second and right at or a little below 6K RPM, i switched over to 3rd and POOF the check engine light comes on! I was sooo pissed!!! I texted RIWWP (Mike) and he kindly called me and we are meeting up tomorrow when i get out of work and he is going to take a look at my coils and wiring for me.
he is the best!!!

But when they changed my engine over, they did put in new wiring, so i dont think that its the wires that are bad but perhaps the wires are loose or coils like some of you are saying..... its annoying cuz i was going to bring my car to get my car inspection yesterday after work and now i have to wait to get this damn light cleared again or it will fail inspection.... i am telling you, i am going to get my car blessed by a priest! I am going to tell him to perform an excorism on that dam thing.... "the power of christ compells you, the power of christ compells you" HAHAHAHA :P

KimRene

Mike i will call ya tomorrow to discuss where we can meet..... you are so awesome!!! I frigin love ya!!!!! muahhhhhhhhhh

KimRene

Hi Voodoo, thank you for the links.... its does verify my situation. Also i do warm up my car every day at least 10 minutes in the morning and afternoon before i leave from work. In the winter, i warm that thing up for 20 minutes sometimes (thats just cause im a girl and i take forever in the morning to get ready....lol) but anywho.... when they replaced my engine they told me that it was a brand new spanking engine. I got a call once after they installed the new engine / motor saying that the compression test failed becuase i had a messed up fuel injection pump. The gas was going into my engine they said and they told me this is definetely what caused my other engine / motor to blow. However if that were the case then why did the other Mazda dealership pick that up? Or did this dealership broke my fuel injection pump and i had no choice but to pay for a new one. Whatever the case is.... all i know is before i had nooooooo problem red lining my car once a day before and now i cant. It wont let me and when i even come close to it the check engine light comes on.... i am praying that its just a loose wire that is causing these misfires becuase the best part of driving an 8 is because we can rev our engines at high rpms.... know what im saying?
