I have a '91 with 248k. When I bought it last year, it had a very rough idle when cold. I replaced the IAC and it solved the problem.
Recently the problem has come back. When cold it will not idle. When warm it idles at about 500rpm and sometimes stalls out. When I give it gas, it runs strong and smooth.
Fuel filter, plugs and wires all changed last year.
I have checked the IAC again, and it is working.
From what I have read, it sounds like it could be the O2 sensor.
Does this sound like a good place to start?
Thanks in advance for any suggestions.
