My stock Evo use to stall after pushing in the clutch ONLY while driving, it was a boost leak on the throttle body seals (common problem). Replacing them fixed it

Now same problem started on my 500hp built Evo. Don't think it has a boost leak, and I'm running an external BOV (ams tuned). Car was running perfect for a long time, just lately it started stalling with clutch in.

Is there any way to EcuFlash higher RPM after the clutch is in so that this does not happen?

After pushing the clutch in RPM seems to drop to about 300 RPM, sometimes it recovers and sometimes it stalls. If I could just get it up 300 more RPM I would be ok. Car idles at 600rpm which I think is too low anyways but it does idle perfect however.

you mean change your idle on ecuflash? your car did not do this before, so your idle could not have just randomly changed from your tune, there is another problem you have to figure out, and you did a boost leak test already?

 

Things I've changed since this started: I flashed the ecu to pass emission to get all monitors to show ready and they do :-). I turned off rear O2 because no cat and I was getting a code.

When I got the car there was no leak. But I'll do another leak tomorrow and report back since I already have a home made adapter to hook up the piping to a compressor.

Ok I did a boost leak test and all my piping from MAF to engine is perfect, not even a little leak.

Funny thing is now that its warmer outside, 50+ degrees the stalling stopped... I'm gonna try cleaning the MAF as it looks pretty dirty.
