I friend of mines car does a wierd thing. If you sit in the drive way and rev it it revs up just fine and sounds fine also. When you get into the car and initally start to go it seems like its a little clumbsy/vibrating, such as when you take your foot off the break and just let it idel, it slowly dumps foward, not a consistent push. Then when you floor it and it gets above like 3.5k rpm the engine keeps reving high but the car doesnt seem to pull anymore it just seems to plateau, but the engine keeps reving up like its pushing something but hte car just isnt being pulled like it should. Almost feels like the trans starts to slip at high rpms. What do you guys think?

 

no one?
