Rough Idle while stopped SXT
I've dumped about 2 grand into trying to figure this out.. compression test rendered my 1st cylinder losing compression. fixed this, was a bad ring, replaced it, resurfaced the head, lapped all my valves, changed all the gaskets, replaced my cam position sensor, replaced MAP sensor...
Engine acts normal, starts normal, until you stop while in gear.. The vehicle drops down to ~500 RPMs, the oil light comes on because theres not enough RPM to pump oil, and after about 30 miles or so the coolant starts boiling.. This is the SOHC 2.0 4 banger.
The IAC looks clean and im lost as far as what to do next to this thing.. Engines pretty much been rebuilt, all cylinders have 120 for compression, no engine codes thrown...
The vehicle only starts slowing idle while in Drive or Reverse.. Stalled 1 time in Reverse since overhaul, and hasnt had any problems in reverse since it stalled out... However in drive the RPMs drop after 30-45 seconds and it starts vibrating pretty good like its about to die.
Any help with this would be amazing, thanks in advance!
