My GTA is idling rough on cold startups?
My '91 GTA with the 305 TPI has been idling pretty rough on cold startups. Is something wrong? What is it? THANKS!

I haven't had the chance to run the codes yet. I'll post them(if any) when I get them. What are some possibilities?

IROC_Z28, He has a "91" cold start injectors stopped in 87 or 88 models, I think.
GTA91, When was the last time you did a tune up? And how long does it idle rough? Does it idle rough just till it goes in close loop?

I think he's right on the cold start injector thing... mine is too new. It had a tuneup not too long ago. It is possibly doing it until it goes into closed loop operation... what would that mean? THX
