I checked the cap and rotor -they were melted! - replaced those - I'm understanding my nect move should be to clean the EGR and IAC (in leau of replacing them)
Unlucky # 7
Thats funny - with my rough idle prob the 7 cylinder was misfiring - did a tune up and found the darn plug was broke in half - and the whole thing was stripped where the plug goesin !
I have done a few things like tune up and TB/fuel injector cleaning - my idle still runs...
I haven't changed the PVC or the IAC - those are my next steps. Here is what I have done so far in order of costliness:
1) oil change/air filter
2) cleaned throttle body
3) replaced fuel filter
4) flushed fuel system and injectors
5) full tune up w/ new wires, rotor, distributor
All of you...
Resolution?
Did you Ever get this fixed???
My 90 vette is having the same problem - I got a tune up, cleaned the throttle body, cleaned the fuel injectors, it still runs rough in idle when it warms up
