i bought a 86 305 tpi iroc with 40k on it ...it sat for a long time so i replaced fuel pump,fuel filter,plugs,wires,o2 sensor,cap and rotor ... when i start it up cold it runs like crap ..wont idle,breaks up etc.. when it warms up it runs great ... it has no codes .. any idea's what i should check next ?? im going to put new bosch injectors in next and try that ... maybe iac motor ???

 

Probably the IAC or the CTS

 

anyone else have a clue as to what could be wrong with this?

 

i cleaned the iac motor and it helped alot ...i also put new gas in it with some fuel injector cleaner so that might of helped to ...i think the gas was old cause after i ran the new gas for awhile it ran alot better ..between the 2 things it made a world of difference ..

 

Thanks, did you ever replace the injectors?

 

if i kept the car the 2 things i wanted to do was change the iac motor and new injectors cause i heard the old injectors from the eighties were garbage ..i didnt put new injectors in ...i have them though ...if you want them there yours ..ill send them out this week ..

 

Those are the exact 2 things I plan on doing first. If you could send those to me I would greatly appreciate it.
