alright guys you gotta help me with this one...its been screwin with me for weeks...ok i got a 85 trans am tpi with auto tranny...heres the deal...its got new plugs, wires, cap, rotor, fuel pump, air filter, throttle body has been cleaned, the timing is fine, the wires arent crossed or arching...when i go to start it cold it takes a while to catch and starts real rough...it will idle at about 2000 and gradually come down until it stalls...to keep it from stalling i have to keep hitting the throttle...this is the thing though...when it reaches operating temperature it idles fine and will start right up...also on the road its terrible when i put the slightest load on it, it will hesitate like crazy and gurggle and gargle...its driving me nuts (no pun intended) PLEASE HELP ME!!

 

My girlfriends '85 Z28 does the same thing I haven't been able to fix it either. You hop on it and it bogs down and wants to die then jumps. I'd like to get an answer on this too. Sorry I cant help with the question but I beileve it must be a common problem on all the early TPIs.

pull the trouble codes, it will be easier for people to help you, if you don't know how check the tech articles, or the faq

 

mines been the same way - but it never throws a code so im thinking its either a clogged/chacked injector, my o2 sensor is bad, or maybe my egr...
