I just installed a Zex wet kit on my car and i am only running a 50 shot but ever since i ran it my car idles really high. like when i first push in the clutch the rpms dive to 900 then jump back up to 1500 then slowly work its way down to 900 after like 20 seconds. Can anyone tell me why this is or what i can do to fix this? Any info would be great!

 

try cleaning the iacv on the back of the intake manifold and also the fifv valve on the bottom of the throttle body

 

it also sounds like you could have a nitrous leak. pumping a small amount of no2 into you engine when you dont want it to. check that then let us know.
