My 91 z28 starts and dies only when cold?
just started having issues with my 91 z...it start then dies, but if you give it gas when starting it it will run and drive fine, just wont idle when the motors cold. drive it for 5 mins its fine. i changed plugs, coolant temp sensor, and oxygen sensor. any idea? its a 350 tpi with auto trans. no codes either

yea...could be possible. i took it to my local shop and left it there a few days and whenever he tried starting it while cold it started and idled fine. so i took it back home and im gonna see if it starts doing it again. he also thought if it wasnt the cts that it could be the the iac motor. so i'll see what happens.

hasnt really done it anymore...although sometimes it stumbles at idle when driving...the rpm gauge will kinda bounce around. i may just change the iac sometime when i get a few bucks.
