Idle /Off Idle Problem PT Cruiser

06 PT 82,000 miles.
Started as in park or neutral hot,it would chug/surge /miss then stall.
Drop it in gear,smooth..no issues.
Morphed into does it in gear also and lite throttle under 2 ,000rpm.
Does this about 30% of the time.
Ran codes ..no codes. But check engine light on.
Replaced, TPS....nope
Idle Motor. ...nope
Intake Temp sensor ...nope.
Plugs...nope.

Ideas, ,theories? ????

If your check engine light is on you have codes. If your code reader cannot display them I would suggest going somewhere else to see if they can read them. If not then you likely have an issue with your OBDII port not communicating. Fix that first

Where did you buy the sensors that you changed? Mopars don't like cheap auto parts store sensors.

OEM off our other PT

Our 07 pt ran poorly and it turned out to be a burnt valve. It had about 70,000 miles on the clock. Somewhat common for those years.

Back to basics..compression test..
