Ok... so i was out driving tonight... and 7k+ in 1st and second gears were acting REALLY wierd.... I had no idea what was wrong... I went ahead and took a video of the issue for you guys... The engine sounded good, smelled good, everything was good except for high rpms...

I figure it was the nanny system saying "you've had too much speed tonight" cuz when i restarted it... the lights flashed for a sec, idle went wierd and needles hopped then it returned to normal... I am no longer having the issue, I've tested it several times since and it doesn't seem to be an issue... However I do seem to be LOSING torque at the high rpms... (though it could be my imagination...) so I dont know... give me your thoughts....

your car has a weak 2nd gear be careful wen you speed

Saphus

Hmmm.. ok.. can you explain a little deeper?? im kindof a newb and this is my first manual... what do you mean by weak second?

Could be a bad ignition coil. Bad spark plug. Bad plug wire. Bad gas. Bad Catalytic Converter. Dirty air filter.
Bad ECU connection. Bad battery connection. Bad ground wire.

Saphus

Thats a little vague... I know the AFs good... Coils, sparkplugs... I've been wanting to upgrade them for awhile... (strapped for cash) Cat... I have had a few 02 sensors out... but the issues fixed themselves

What?

Rotore_787

if its your first MT then take it easy because the rx8 has a very weak 2nd gear meaning its is to fok it up

Saphus

Uhhhh... Kinda wish I woulda known that previously... i chirp it a minimum of once a day..... like super quick shift... half clutch... like race style, aggressively... ****.

Ignition sparks & coils

Rotore_787

yes dont drave like that until your completely comfortable with the car and know how much of a beating it can take.

no its not the ignition sparks or coils its just that you were beating on it to hard thats why it acted up when u started it again the same thing happened to me

Saphus

Easy... Thank you for that... you know, I'm laying here trying to sleep (got to be up @ 6:30 for work.) and Im beating myself up over this car and all the money I'm gonna have to spend yada yada yada...

And I decided to get back on here for a quick second more... thank you for putting my mind at ease.

I think just to be safe, Im gonna go ahead and do a full royal purple oil change tomorrow, set myself up for a transmission flush. I'll probably have them inspect all the ignition spark and coils too.. (its 68,000 miles... I bought it at 60... )
I have no idea what the previous owner did or did not do... all I know is that its getting pretty close to time for an oil change.

Um... do you think I can expect my high rpm torque to return??

I beat my crap out and it still works ...

might have something to do with my *crazy* maintenance ? I dunno

if it dies, Im gonna hunt for the 09 tranny. alright ! gigggy giggy ~

Rotore_787

keep beating your car like that and the tranny will be gone be sure you didnt split the teeth on 2nd and the gear shaft

oh and by the way i saw your video step on the clutch hard then haft way an is your check engine light on?

Rotore_787

why its the same tranny?

and you beat yours but i bet you dont step on the clutch half way and shift hard... Its his first MT we all been there

Nubo

You could give a better explanation of the video. Not sure what the complaint is, but I am guessing you couldn't get past 8,000 rpm? I'm not sure why people are saying trans problem.... The recovery on restart seems to indicate that the computer was limiting you. Not normal for a warm engine. It's never stopped me from redline and fuel cutoff is normally well above 9,000. Didn't see CEL flash, but you could check for error codes.

And why did you tag the vid with "Sandwich"?

rotary.enthusiast

Yeah, this has nothing to do with the transmission. Granted if you always do the 1-2 shift like you say you are your synchros and not long after your 2nd gear will be toast.

This could be any number of about 50 different things. My rule of thumb for any car: if it won't fire up, or doesn't seem to be running properly when it does, check the ignition system. Plugs, coils, and wires are the most common offenders.

I shift carefully, just to be sure that I wont "slip" into the wrong one & the gear is all the way "in"

This transmission is known to be ok for regular street use, but suck *** under racing condition.

Mazda/Aisin knows about it, and made numerous improvements on the 09 tranny, and it should be direct bolt on with no modification. (certain gear ratio changed tho)

Saphus

Alright issue returned... Now, today when it came on, it was after I had been "Tracking" an empty parking lot with dividers (not doing doughnuts... actually using the dividers and the buildings as a large track) my dsc was off... and I was very gentle with my shifts (I have been ever since my discussion with **EDIT** ROTORE [my bad]) lot of downshifting though at one point in the track I was inducing SOME oversteer but not much...

I never put it at redline during this time.

On my way back home I went around a corner off of a stop light w/o shifting into second and ran it up to redline... same situation as before (in the video) only this time I realized I forgot to mention something on the first issue...

around 7500 RPM @ WOT (while having this problem) the Gas Pedal Goes limp (loses its tension) I Feel this may have been a large factor that I forgot to mention the first time this issue came up.

Rotore_787

clueless at this point

Old Rotor

When you say"Gas Pedal Goes limp" do you mean the engine is not responding to your right foot? Maybe it's as if there is a bind in its linkage? Please give some more history on your car.....

Please try to be a little more descriptive in your title -

Uhhh... WTF...

just doesn't cut it.



S

Saphus

well... I figured the title wouldn't but I thought the video might....

When I say the pedal goes limp (thanks btw whoever changed my thread title ????) It loses its tension... As in anyone who wears race "style" shoes (Ie Puma speed cats) with very thin soles can feel every vibration and change in their pedals... Well around 7500 I guess the best way to describe it... it stops "vibrating" ?? the way it does under WOT (if you know what I'm sayin) its like pushing the pedal while the cars off.

I guess It feels like a fuel cut

Now I just went ahead disconnected my negative terminal re-attached and am no longer having the issue...

So is this an over-active Nanny program or what?

When I say the pedal goes limp. It loses its tension...

That is, of course, impossible.

The pedal is only connected to the computer, it is just a couple of resistors and a spring - there is no connection whatsoever to the engine itself.

....it's all in your mind !

that definately is weird It does sound like it's the ecu limiting you but i don't know y if would be when it's warm and one y does it start limiting you at 8k not like 5k? I know what you mean about the pedal i think it is a ecu prob....

Really!?

There have been plenty of cases of the pedal coming apart from the metal it's attached to. Oh, and apparently it occasionally needs lubricated? Or so my dealer has done.

swoope

iTrader: (5)

read close the gas pedal is what is claimed to go limp. does not happen.

and to the op..

does this happen in left hand turns???

sounds like a fuel pump.. but it also could be the apv valves, coils, wires, plugs..

seeing the video. could be cat or maybe time for a new motor..
