heya guys

my car at the moment does not want to idle properly, its idling up and down like a ****, any idea what causes it ???

does running rich on idle will cause that sort of problem ???

its full built b18c1 with JG manifold

thank you

vacum line ?

Cyber ITR

cyph3r

did you use teh stock throttle body on the jg?

Cyber ITR

yes i did , indeed sir

why is that ??

cyph3r

with the car running and jumping like that look inside the stock throttle body.
there are 2 holes on teh left side
take your finger while the car is still running and plug the top one. if that fixes it replace the iacv
if not plug try to plug the bottom one. if it stops now the its the fast idle valve

if its the fast idle remove it and take the end closes to the firewall off. inside screw it all the way in and replace the fast idle back on the car.
should be fixed

Cyber ITR

sweet ill try to do that tomorrow

thanks a lot for your info

Cyber ITR

and uh do you think by bypassing the coolant on the intake manifold will help ??
