the car is reving by it self when i start the car i was wondering if anyone had any ideas on what it could be and what i could look for to check out. i checked the hoses and they are all in the right spots and the gaskets are good too.
let me know if you have any ideas!
Thanks

 

This happened to me when I swapped a y7 manifold for a y8. The problem was that I didn't get all of the old gasket off of the engine head and it caused vacuum leaks. So check this, and check that all of your hoses for holes. Make sure you torqued every bolt to spec.

 

sounds like you have a vacuum leak.. spray some carb or brake cleaner around the sealed areas until it revs higher. then you know where the leak is.

 

ok yeah im going to go check it out now. i was thinking it was a vac. leak also but just wanted others opinions but i got all the old gasket off the throttle body and the manifold so i dont think thats it ill check anyway tho. but ill go check for vac. leaks right now and see if thats one of the problems.
Thanks

 

Its definitely a vacumn leak, you messed up somewhere...

 

either vacuum or a tps sensor. Rip the Intake off again and like they said check for old gasket. Not the TB, the intake itself going to the head. Check for all the vacuum hoses make sure there all connected.

 

ok thanks a bunch im hopefully ganna finally have time to finaly get it fixed tomorrow
