Hey all,
I know I'm not that well known around here, and that there are some similar problems to mine on this board but none of them seem to completely address my issue. Here goes...
I drive a 2002 Ecotec Z-24 5-speed(Canadian) and most times when I just start the car and drive, when I hit the clutch the revs will drop really fast down to about 400RPM and almost stall out and they won't level off until the car comes to a complete stop, and now it will do this at about 5-6 stop signs and then will start to drive somewhat normally. Also, when the idle is levelled off at about 1000RPM and I turn on the A/C the idle will dip down to 500 for a second or two and then level off, but won't do it after the car has levelled off from stopping 5-6 times. I have had the recall done for the ECU/PCM to no avail, and the only code I ever thorw is P0440 (catalytic converter related). Any ideas here guys? Other than this the car drives fine, but makes for a very uncomfortable drive because even when shifting from 1-2 I have to let the clutch out really fast because of how fast the revs dip until the car decides to level off. And just as a side note, it's not temp related, as even after driving for a while if I shut it off and start it right back up it will start all over again.
