Hey guys I have a s14 sr20det and here are my following problems:

On cold start car jumps to idle but hesitates then wants to die even when giving is gas when I let off it will still die then after car is warm sometimes it will start up and idle fine.

Idling has never been perfect with this car it will continue to move up or down even after cleaning IACV

When car is running after changing gears then going into neutral car "sometimes" dies.

Everything fueling wise has been replaced; Fuel pump. Injectors . FPR also set at right psi

Also on start up car runs rich like 10-11 then the times it runs right AFR is normal 14.5-15.5

No boost leaks from what I see or hear nothing is unplugged etc.

My mods; Rs enthaply tune for following mods

Stock internal SR
Z32 Maf
FMIC
Full 3 inch Exhaust
550cc injectors
Electronic Boost controller set to 10-11
Aem AFR and AEM boost
