Sometimes when I'm at a light I blip the throttle and the engine
vibrates like it's going to stall. It doesn't do it on a regular basis
I was thinking the revs lower to almost a stall and that causes
the vibration then it bounces back to normal RPM and everythings fine. I can't get the car to do it at the dealership
Any Ideas? I was thinking the idle should be turned up or something to compensate
Thanks

Is your A/C on? If it is, then it's due to the parasitic draw of the A/C compressor cycling on. When the engine hits those low revs, the computer doesn't quite catch it in time but after a few goes, it learns and it won't do it for a while till you don't use the A/C for a while. Then, when you use the A/C again, the computer will have "forgotten" and it'll need to learn it again. Once it's learned, and you use the A/C regularly, it probably will have an easier time "remembering". PITA isn't it?

Wow! I was wondering about that too! My new '02 actually stalled the other morning doing this! I am not alone and now I actually have the answer! So, nothing to worry about
