Re: 1986 camaro runs horrible whin its cold need help

Is this the year with what they call the 9th injector? It's supposed to act like a choke and give the engine extra fuel. You didn't by pass the coolant lines thru the air intake did you?

The ninth injector was used on 1985-1988 motors. Yours should have it then.

Re: 1986 camaro runs horrible whin its cold need help

yea it has the ninth injector... i did not bypass the throttle body collant hoses either.... all i know is it was running fine before i took it apart the only thing was that it takes a while for it to idle down when you first start it its idles about 1000 RPMs and then once its warmed up it idles about 600 to 700 rpms and when its warm it drives and runs fine? confusing i know everything is hooked back up i checked everything again
thoughts?

What did you take apart that may have caused your problem? Also try posting this under the tpi section. There may be more knowledgable people there. I've never had a tpi system.
