every time I have a weird and unique problem with my car, I assume i'm the only one the earth with that problem...it's always surprising to see someone else has the exact same problem, but it's also comforting..haha..
have you done anything with the throttle body? I think it's something to do with the TB because the TB would have a lot to do with allowing the car to warm up (adjusting air/vuel....choking basically)....if it's not doing that right, it would explain why the car runs like crap at first....
what have you tried thus far to check it? i always thought it was because my IAC was bad, but i replaced that and it still does it...it's just really annoying when i'm cruising through traffic...if you hold on your throttle around 2-3 grand, does it pop and miss? try it...just put it in neutral and barely lay on the gas...mine misses, and this is what causes the car to wiggle and jerk about...but if I nail the throttle, all is well..i don't get it...
