okay so i own a 92 hatch with a d16z6 swap. my problem is that since i change my throttle body it idle from 2.5-3 rpm back and forth. if i open the throttle body a little bit it rev the motor all the way to redline and wont stop until i turn off the car. But if i cover the throttle body with my hands it goes back to normal, so i have a leak somewhere right? i never had that problem until i change the throttle body. i also change the gasket too! tighten every bolt tight and plug all the line in. please help vacuum line is plug in.

 

any one!?

 

bump!

 

is anything cracked did you try a lil silocone around the gasket. It might not fit flush.

 

no crack and haven't tried silicon yet. maybe i should.

 

just want to say it was the fitv (fast idle thermal valve). got it fix!

 

i dont know try switching your tps and map sensor plugs... maybe they are hooked up wrong...
