this has only happened the past 3 times i have driven my car but it worrys the hell out of me. I start it up and when i put it in gear to go i almost feels like it wants to die...so the last time it happend i mashed the gas it started to take off and then hesistated and jerked at 1500rpms...then about 3 seconds after that the cars takes off like normal and acts fine. It only seems to happen if i have left the car sitting for awhile, like overnight! I think it isnt getting enough fuel or it might be bad gas does anyone else experience this? my car only has 12k miles on it, does it need a tune up?

no you won't need a new engine. i'm getting a new engine cause i let sears "change" my oil. but when they "changed" my oil, they didn't put any back in
