I had a problem it would idle at 1 and half also!

Check:
1.Vaccum Leaks
2.Try to check if your senors are pluged in!
3. Try to do a Idle Troubleshooter Test

But in the end my problem was that my senor (IAV) was messed up

when it starts it idles at 1.5k rpm is normal warming up.... well if you are saying it idles at 1.5k rpm is warmed up then its bad

joseph weldon

does it idle at 1.5 rpm as in just sits there when ticking over

joseph weldon

that's normal with the SK2 mani man I have the same a gsr motor with the SK2 mani and was told b4 I got it fiited it will idle higher around 1.5 rpm

Check your fitv on the bottom of your throttle body, that's what was wrong with my gsr swap.... And mine also idles at 1500rpm with a skunk2 Intake mani.....

dang thats weird, take a bottle of brake cleaner and spray it between the tb and manifold, maybe theres a gap where air escapes, also try it were the mani meets the head. if idle goes down while spraying the brake cleaner you will need a new gasket.
