i love this car but i hate it cuz i cant figure out what the problem is, was hoping someone could point me in the right direction.

just got it outta the shop after 10 weeks of dude trying to figure it out

ive replaced iac, tps, map, maf, engie temp sensors, now it wont stay running unless its in nuetral,

new distributor, cap button plugs wires,
replaced numerous vacume hoses,

if i try to start it it runs for about 30 seconds tehn stalls out

and just found yesterday that if i put it in nuetral it runs and idles fine

just got all new seals on valve covers intake manifold,
new fuel pump/filter,
new ecm
ignition coil
checked fuel injectors they seem to be fine


any help or ideas would be greatly appreciated i swear ive checked everythin hopeing its just something simple im looking over but im not sure thats why im here asking


Thanks,
Justin

 

Maladjusted throttle valve, and the IAC does not have enough range to compensate ?? Also make sure the EGR is closed at idle speed.

 

if u have adjustable idle screw on the tb try adjusting it as though u were setting the idle higher.

 

Also, its a long shot but maybe your cat is clogged? Does the car misfire at all? Any problems shifting gears? I have the exact same camaro, never had these symptoms.
