My engine hesitates at a stop, and sometimes while driving, now when I put it in neutral the hesitates stop. I've changed the spark plugs, which helped alot, but did not solve the problem. I only had this car for two weeks, so i don't know much about it. I've read several posts on here about this problem, but no one ever mentioned when the car is in neutral it don't hesitate. When driving you can feel the car hissing, or putting a bit. Its a 93, any advice would help, thanks. CEL come on sometimes, but not all the time, only drove the car 4 times, twice the CEL came on.
