HELP! Engine revs up and down during first day crank
Hi,
when I crank my car for the first time of the day - engine cold, it revs up to the regular cold cranking rpm - around 2200 rpm. after about 30 sec it starts jumping down to 1000, back up to 2200, down to 1000, back up to 2200. It does it for about 2-3min until the engine is warmed up. Future cranks it acts fine, only if the engine has been sitting for a couple of hours and is cold. Temperature here is normal, i'd say bout 80degrees. I'm in Germany and dont really want to take it to a dealership as the have no f... clue about this car over here. Do we have like a cold cranking module or something that could have gone bad? Got about 35K miles on it, 2005, 6 speed manual Any advise would be great. I already tried reseting the ECU, didnt do anything for me :( HELP! |
mine does almost the exacty same thing when cold. I have 05 6 speed manual with about 55K kilometres on it.
The revs will start bouncing around almost immediately until the engine is warmed up. All recalls and tsb's are up to date and the engine runs fine after that. ?? |
mine does that too.
reminds me of my friends built camaro. he has a variable cylinder head? i dont know. but it revs all over the place before it settles down and he can drive. |
if you have the clutch in, does it do it? if not likely you have a failing neutral pos switch.
i have the issue, it comes and goes. beers :beer: |
thanks for the tip.
|
if the rev jumps up & down, Up & down, up and down ... for a couple of minutes until warm up. it could be ur neutral switch acting up. it happened to me once. but only when it was really cold.
|
Ok.. what if it doesn't really jump up & down repeatedly, but has a flashing CEL and a smell (as if someone lit a match) coming from the exhaust? The car trembled a bit and the engine had a much louder sound (very hard to describe). Once the engine warmed up.. the trembles stopped and the CEL stayed solid. It happened this evening.
|
dry apex seal. option one.
bad cat. option two.. beers :beer: |
Neutral switch is the best bet.
|
^Neutral Switch??
Took it to Advance Auto so they can read the CEL code(s).. I have a small emissions leak and... Misfire on Cylinder 2.... I know it means a Rotor..I believe that's the rear Rotor? After searching... I found that it could be a serious of things.. Plugs, Wires, Coils..... Now, you guys have added Apex Seals, Cat, and Neutral Switch... Could anyone be so kind and it explain that to me a lil' better?? |

Thank you for your prompt response... :)
Are the rotors covered under the Engine Warranty?? |

Are the rotors covered under the Engine Warranty?? likely everything is.. how many miles on your car? and you are where? you can pm me if you like.. beers :beer: |
It's cool...
I have about 44,000 miles... but the years caught up to me before the miles.. so my "warranty" per say has expired. But with the new extended engine warranty, I was wondering if it covered that... Ironically enough.. I too am from Orlando, FL lol. |

Ironically enough..

^^Thank you Easy...I believe it to be true... :)

Let us know what they say it is BumbleBee

Can you believe that my Bee has BEEn at the dealer for 2 days now????
Day 1: Ran the heck out of the car...we ran some tests..can't figure out what's wrong..is it ok if we keep it until tomorrow..we want to start it from a cold start in the morning... I'l call you in the morning. Day 2: It's...after 1pm..so I call...left a VM....at about 3pm...Ring.. Hey we looked at it in the morning, but honestly we haven't been able to get back to it..You're welcome to pick it up and bring it back tomorrow morning or leave it another night for further testing... I said Keep it! No sense in picking it up just to turn around and bring it back. It's now 2:42pm no call as of yet. If I don't get a call by 3pm...I'm going to go get it.. They close at 4pm on Saturdays..! |
Is the SSV opening and closing when the idle hunts?? you might want to check the solenoid and pull the vac line off the actuator to check and see if it stops...

It did this on my original engine, and it does it on my brand new one, so I'm sure it isn't indicative of engine problems as both my new and old were perfectly fine. |
I've had the same problem on an older Prelude.
The problem was 3 bad TB valves. Ended up replacing the entire TB :( |
Well...it appears I have a bad coil.
From what they told me about the Extended Warranty...was that it only covers 1 bad part... in other words... it only covers 1 coil... I have to come out of pocket for the other 3 coils (if I choose to change them) and the plugs and wires. I can except the the plugs and wires, since that's maintenance... but jeez...they can't cover the other 3 coils. No! Soooo a 5 day slumber party at the Dealer for nothing... I took the car and I'm taking it somewhere else to get the job done for a heck of a lot less $$$... Would anyone assist me in some ball park figures on: Coils Plugs Wires? Thank you.. :) |
the 5 year 60k mile powertrain warranty covers everything you are talking about..
that was extended with recall 4206f ask the dealer you are working with it if it was done.. btw, pm me if they dont fix it. beers :beer: |
I believe that recall ONLY said (on the paperwork)
Changed Spark Plugs I'll have to double check.... But it DID NOT say wires and coils.... was this recall around Oct of 2007?? |

So, what you're saying is.... This should be covered and they're pulling my leg..correct?
If so, I don't understand why they do that!! Why do people have to lie??!! You make a huge investment for them to risk ruining it for ya.... I'm driving around with a car risking more damage and me stranded... trying to make a decision and get to the bottom of this.... It's ridiculous!! |
Thats why even if i still have 100% warranty i still buy and fix the parts myself !
i have a shop and get everything 50% off i just accidentally broke my tpms sensor and i got it half price you just need proof that you own a shop and dealerships stiff arm you!!! when i bought my rx8 it didnt have the spoiler i asked for so i was given a voucher and had an appointed day when i went the guy goes ohhh your ac isnt working right im like stfu im a mechanic your telling me its not working !! look just got put my wing on and i just left (whic took an entire f**** day !! ) i dropped it off as soon as the dealer opened i absolutely hate them !! |
well, mine is still reving up and down when started. But its not only when its cold now. It does it whenever its in neutral. Soon as I press the clutch - it idles normal. I let off the clutch, it revs up and down.
Plus i got a cel now too. When i tried to read it out - keeps saying it cant communicate with the vehicle. Yet, the scantool powers on, and the only source of power is the odbII plug so.....??? Fuc.... where is the neutral switch and how do i replace it? |
UPDATE..!!!!!!
I finally, got my car fixed.... It seems the dealer I was going to didn't take care of me as suspected. Let's just say that I won't bee going there EVER!!! The place I took it to, actually took all 4 coils out, showed and explained how they looked and why they looked like that... He even told me it had over 400 misfires... I was never given that much detail beefore! All 4 were bad.... when they told me just 1 was gone! Now, it explains why my car was running so crappy! It's amazing the power I have again... I will however, need a new battery soon... he mentioned I had a bad cell. So any suggestions on where I can get a Red or Yellow Top for a decent price?? Thank you! |
auto zone has a rebate on both right now. i know because i did not get it. was to early..
get the red top.. and read a bit before you order it... beers :beer: |
The pepboys in my area had a deal where the red top dropped to $125 from $160 and then had a $25 rebate so its only $100 and autozone matched that. Not sure how much a yellow top would be.
