Guys i need your help, something fishy is going on. Ok so for the past 3 weeks my car has been loosing its acceleration ( for lack of a better term not going anywhere when i hit the gas), this usually happens when im leaving school. ill be at a stop (1-3 minutes lots of people trying to leave) and finally when its my turn to go ahead my car wont budge. ill press on the gas and nothing. i first made sure i hadn't hit the gear into neutral, nope it was in drive. so i put the car in park turned it off and turned it back on again then everything worked. so far this has happened 3 times, once when i was on a hill (at a stop) and i rolled back down almost smacking into the car behind me.
- why is this happening?!! what can i do? does any1 have any ideas plz.
