So after i put a new engine in my 95 the idle revs up and down. It does it all the time. Only did it after the swap and it has the original sensors and stuff from the original IM/TB. I need help its damn annoying. Thanks in advance

 

Have you tried cleaning out your IACV? or if that doesnt work about using another one?

 

clean iacv. check for all the vacume leak. all the seals, exhaust and intake manifold gaskets.. and ground wires.

 

but it didnt do it on the old engine. only this one

 

ground wires will do make it do that? never knew that. alright ill check all that stuff tomorrow. thanks for the help

 

did you swap it for the same engine?

 

Bleed the coolant system?
