Alright. I read through the threads and could not quite find a direct answer to the problems I'm having.

1) The car has been running very rough when stopped at a red light and left in drive. When I put it in neutral the heavy shaking stops. This specifically happens prior to when the car has been warmed up. But I live in San Diego and it'll happen on an 80 degree day.

2) There is a hesitation when shifting from first to second then from second to third. By hesitation I mean the car revs a little then shifts to the next gear (almost too early before the rpm's should dictate)

I read that this could be a vacuum line issue but I'm having more of a gradual shift then a jolting shift. Also, its strange that the shaking only happens when the car is in drive.

What do you guys think?
