idle on a 89
I have a problem with the idle on my 89 when stoped at a light it has a slight miss but it pull great, RPM stay at 600 at idle. I have change the plugs,cap and roter. I have also changed the ignition control module. A few months ago I cleaned the IAC and tb. Could the IAC and TB gummed up after 3000 miles ??? The plug wires look great not dry or cracked. I also changed the fuel filter. Any ideas ???

If youre not getting any codes: IAC, plug wires. My bet is that its just one or two plug wires, replace all of them.
