I just got back my car from painting and it was running totally fine before I had brought it in. One of the problems that had occurred was that they flooded the car and I had to go there to get it unflooded. The motor was just installed with about 300 miles on it before going to the shop. When I got the car back, the car was idling at around 100rpm. The car was barely alive but it constatly idled at that level. I let the car run getting it to operating temps but still no change. When I drove the car it just wanted to die I had to rev it higher to get it from dying out when i engaged the clutch. I added gas and drove the car a little more, all of a sudden it sputtered and then it started runnning fine again. This was probably after a half mile to a mile worth of driving after. I was wondering what could of caused this type of thing to occur? Because of this could I of caused any damage to the car? Right now the car seems to be driving fine. The reason I post this question is to make sure I hadn't done anything foolish and risked losing this second motor.

dirty plugs finally cleaned themselves when you actually drove the car

its prolly the battery/ battery terminals, wierd things happen when you get the car back from the body shop like that

cool thank you for the replies. freaked the hell outta me when it happened.

when both my 1st gen and 3rd gen flooded, It would take a few hundred miles for the idle to return and the car to drive normal again. Although I usually did swap my plugs out everytime it would flood, it still would take a few hundred to return to normal. I miss my 1st gen BTW.
