3500 idle revs after exhaust change

[Jeepy-chan]

Changed my exhaust manifold after it cracked and replaced it..now my 2.5 L Jeep is revving 3500 at start up and won't come down.. What is the problem?

tps sensor plugged in?

Vac line maybe. Mine did that after I lost the evap canister and some guy at a junkyard in Waterloo stuck a screw in the vac line and fixed it

Mine would do that when my tps was messed up. It was even a new one. I guess I just picked up a bad one because replacing it fixed the issue.

Would a leak around the injectors cause this?

Idk where the leak is or if that's it

Did you remove the fuel rail?

 

[Jeepy-chan]

I fixed it, one of the lines had a hole in it
