hey guys i have a 2000 sunfire gt 4 speed automatic and everything was fine few hours ago and when i left my boys house to come home i noticed when i took off the car would like bogg out or sputter up til like 30 mph then it would stop and i noticed that this happens only sometimes and mostly when i slow down and then proceed, could this be my tranny going out or what, im stumped.

nevermind, my dad put in this fuel stuff and apparently there was water in the gas so everything seems to be fine now, thanks anyways

did you put 7-11 gas in it??? if you did there was your problem. see the thing is that when 7-11 gets there gas they dnt filter out the water and it causes it to do that sputtering bogging type of thing.
