so i just looked a the throttle body and it looks cleaned so i didnt clean it so i dont think it is.. but heres the situation,
when i start up the car and accelerte it, it will go up to 7-8000rpm! but it will only last for a few seconds no more than 5 seconds, after that it will not move past 1500rpm!its like its stuck right there! and it keeps doing that!! as long i start up the car it goes all out after that bam slower than a turtle! but there is something i need to mention, the car got in to an accident so the abs sensor is on, airbag is on cause it got dyployed.. no check engine. any ideas? ive been very pissed about this car!
