Default Start-up hickups...

I guess I am not the first one to mention this happening, and it happens regularely, however last week it was real extreme. I started the car, started to move and stalled at the middle of the street. Completely! I tried to restart but could not. On one try a massive double could of black smoke/soot appeared. That was real impressive...The car finally restarted about 2 minutes later. Imagine if I was not alone, that would be pretty embarassing. Any ideas how to avoid this and wha is causing this situation?

anytime i hear about a car stalling or poor
idling, the first suspect is a dirty MAF sensor,
or the throttle body needs a cleaning

No, its idling fine afterwards, but there are ( those are ) HICKUPS!!!! Its only when you start it after it has been standing overnight or longer. I am sort of getting use to it. Surprized no-one else has it...

haven't really heard of this before, but yeah, check the MAF and make sure it's on right and clean.

Definitely go buy some CRC Maf/Throttle Body Cleaner and clean both up real good. If you still have problems, maybe get it checked out.

I think the problem is the people who light it off COLD, then put it in gear and go right away. Mine does the same thing. I give it 10 seconds after a cold start to get the O2's to warm up a bit. If you dont it starts chugging and idling crappy. Because the O2's read inaccurate lean and tell the ecu to add fuel.

I wait at least 10 seconds as well. The car has no timing upon startup according to my aeroforce gauge. I wait for the timing to start going up, it goes into closed loop very quickly.

If I don't wait at least 30 seconds on cold start, my exhaust will backfire/pop on the 1-2 shift and then it's fine. I think it's just unburnt fuel in the exhaust. This only happened after I installed my CAI and tune. No big deal, I just wait 30 seconds. It usually takes that long to back out of my garage and down my driveway.
