After a/t to m/t swap, 2g will stall when clutch is depressed...

[crankin2G]

After the swap from a/t to m/t, while I am driving, if I depress the clutch and am running a considerable RPM, engine will completely die...if I motor brake, it doesn't stall, and will always start right back up...it's like if I run a high rpm to idle fast (such as putting it in neutral to stop at a red light) it stalls. Vaccuum, maybe?

I'm having a similar problem, was wondering if anyone could offer any solutions.

I'll be it a 3000+ rpm then when I press clutch to put the tranny into neutral, the car's rpms will drop very low...almost to stall. It has stalled on a couple of occasions.

I have a similar issue. If I push in the clutch and rev up..then let off gas it nearly dies.

This weekend I'm going to be following the VFAQ procedure for setting base idle. This centers the ISC and while you set the idle allowing it maximum control over your idle speed. Mind you the car idles decent if I let the rpms drop slowly down to idle speed.

I think I'll get around to this saturday afternoon. I'll post when I'm finished with results.

PS. My other DSM that runs well..after you start it it idles high for awhile. My car "problem dsm" doesn't. what about you two? If that is the case that might confirm the ISC theory.

I've always heard/read that stalling when the clutch is pushed in is usually due to either a big boost leak or Crank Walk. So I would start checking for boost leaks . . . .

Ya. I've been leaning towards boost leak myself. This problem started after I installed the BOV. The flange I was using with the old intercooler piping for the TurboXS RFL was not compatible with the new piping, so we drilled new screw holes in it. I used some liquid gasket on it and that fixed the problem. Also, I cut the little recirculation tube from the intake to make it a bit smaller, and used some liquid gasket on that.
