My motor won't run on idle if my foot is off the gas. Motor runs and idle just fine if I let it have an massive air leak. What I need to set valve clearance, because I have it at OE spec.

The head & Euro R manifold are port and polish, with stock GSR throttle body for now. Crower stage 2 with springs and retainers. Stock bottom end.

Thanks for the helps.

 

modified primary crower 2's or stock primaries?
engine management?
Tuning?
check engine lights?
cam timing?
ignition timing?

 

Stock primaries.
Stock H22 base map that ran fine while it was stock motor.
No tune yet, because it would not idle/run.
No check engine light.
Cams are at 0,0
Timing is at 16 degree.

Thank you for the help.

 

i didnt ask about the cam marks. I asked if you double checked that the cam timing is proper in relation to the crank timing gear and TDC

 

Oh, everything was checked many times. Even the valve clearances were checked too.

 

my single cam with a stage 2 crower is doing the same thing, i just put the cam in and with the valve lash WAY out of spec and making all kinds of noise it would idle, with it properly set to the closest OE spec which for me is .007 IN and .009 EX the car wont idle. Once my car has cooled down again and I am able to adjust the valve lash again I am going to try to adjust to the looser side of the specs.
