Hey guys,
Just got an Evo 6 TME, it is the first turboed car I've ever driven was wondering if it is normal that when i rev to about 7.5k RPM and then clutch in and brake the car stalls, is there away to fix this, sorry if its a stupid question, just slightly concerned and having no experience with turbos i have no idea, it occurred to me that it could be something to do with the ECU, but i have limited technical knowledge about engines and truthfully have zero clues
 
its either yes or no. does it psccchhht really loud when you change gears?

if yes, you have a VTA bov and that is the problem.

if no, it's something else and ill have to think more
 
I have noticed in my 9 that some times when clutching in from high revs that the revs drop to 500shaking point sometimes but never stalls, wall told it was a fuel issue due to the change in demand
 
im not really sure still, when i change gears it makes a wooshing noise not really sure if its loud or not it doesnt make the noise it does in gran turismo 5 when u get the waistgate upgrade lol :D sorry if im not being helpful ^_^
 
have you taken it to a mechanic? we get so may of these questions about stalling/poor idle that can be so quickly and easily fixed by taking it to an auto electrician or mechanic
it could be the idle speed controller or trottle position sensor, if they are anything like the lancer ones which have a habbit of fking themselves over ever couple of years if ur unlucky
 
What res said, though it may be the more ezpensive option, you'll know the mech can diagnose and fix the problem.

Adding food to thought, could it be with such a big drop in revs that the engine is being flooded with excess fuel?
 
Best way to tell is get it on a gas analyser... it might be a massive lean-out condition too.. causing starvation...or as Skip says above, flooding. A mechanic will be able to see, with the gas analyser if it is overfuelling or underfuelling, because most car maps will be as close to stoichiometric as possible. Going to a mechanic is the first step, if he suspects it may be a tabling issue, you might need to find a more sophisticated workshop.

Coincidentally, a problem like this stunned a few of us Italian bikers for the longest time... even seasoned mechanics never picked it. It turned out that the printed rheostat circuit of the TPS was worn in the mid-range and people had continually tuned it out to suit... when high revs were applied the bike kept overfuelling.

Good luck, sounds like we need some pics of your baby real soon!
