I have a 1993 dodge spirit, 2.5L engine vin k with 150k miles on it. It is auto trans 3 speed. My car will not idle.I have new plugs, cap and rotor, wires, o2 sensor, temp sensor, ect. When the problem first occurred, my daughter was driving it and I didn't believe her because it would not happen again for at least a month then it happened with more frequency. Now it is all the time.I have checked for vacuum leaks, trans. Converter engagement, hall effects pickup, fuel, map sensor, evap. Purge solenoid, fuel pressure, canister, fuel filter, tbi gasket and probably other things I can't recall at the moment. When I first start the car sometimes it runs well for a minute or two.I have scanned it with the autoxray ez scan 6000. There are no codes. This is the live data with the engine cold at idle: o2 bank1 pos 1.94v cool temp78 degrees, cool sensor2.2, throttle pos.6 min.6batt volts14.5, map sensor16.5-17inhg, map volts2.3-2.7ais61 steps, adapt.
