This is regarding my 1990 Mitsubishi Mirage 1.5l, exe, 4dr auto trans w A/C - I am original owner. I have replaced the transmission and or torque converter on this car. I even replaced the entire motor but no change. As well as: ICS, ECU, injectors, plugs wires, mounts, O2 sensor, timing belt. I have also had the car smoked for vacuum leaks - non found. aI have also cleaned the throttle body.

My detailed observations are: starts runs fine after COLD -really cold start. Within about 3 mins or as soon as I hear coolant moving / thermostat opening vibrations begin and get worse as engine gets warmer. Once warm vibrations are bad in gear and mostly go away out of gear. The car is trying to run right and vibrations erratically resolve and come back - vary rarely. Once warm and vibrating, they are exacerbated/lessened by the application/use/discontinuation of brakes, headlights, a/c. even turning the steering wheel.

I am quite certain it is some sensor or wire or electrical issue
