Rough idle and stall out at cold start
Have an 87 Iroc 305 TPI Automatic. At startup it always idles rough, but soon catches idle and idles good, but sometimes it stalls out after starting up. Any ideas what it could be? Thanks.

Re: Rough idle and stall out at cold start
I'd start by checking and cleaning the IAC Valve, it could be gummed up causing it not to idle correctly.
