I'm Awesome
before heading home from work, i re-gapped both sp to .060 and installed back in. Cleared CEL and headed home. CEL came back on after driving about 20 miles only for cyl 2 misfire, not random as before.
Early morning cold weather has an effect on misfires and idle. Some reving up and down by itself only in cold weather makes me think it’s maybe the IAC or a small vacuum leak. I had previously cleaned the IAC with some throttle body cleaner.
New parts will be here tomorrow, as mentioned earlier, all plugs will be gapped to .045 and I’ll go from there. Maybe will purchase a new Delphi IAC as my current is what I’m assuming original, so over 25 years.
All 4 O2 sensors are getting replaced as well as soon as I squash this misfire issue.
