Been having quick intermittent check engine problems (while driving, then disappears, never been quick enough to grab the code) with the Thunderbird for years after a tornado incident in 1999 (Carport fell on top of car and damaged the rooftop and sails.) Car was restored after.
Car will stall sometimes from park to gear and reverse (RPM drops to 300 then stalls). Car taken to professional years ago and never fixed. He replaced all common sensors and spark plugs that can cause this problem(The professional never gaped the plugs properly). Recently I cleaned IAC Valve(Passed resistance check) and throttle body, and changed spark plugs (Noticed the plugs looked like some carbon buildup must be running rich). I just thought I would mention this. Don't know much about the systems of the car. Also we had a 01 Dodge Viper with the same exact problem that we sold because of this problem that no one could fix.
Do you have the ECM pinout diagram for the car? And also the diagram that includes the primary electrical systems that run off the ECM?
I really do appreciate this!
have the same problem?
