Car quit while driving, restarted after a few min. Quit again 20 min later. Let sit and restarted next day, quit again in 20 min. Towed it home. Drained fuel tank and replaced pump, strainer and filter. Started and ran at idle 20 min, quit. So far have replaced IAC, inlet air temp sensor, crank position sensor, checked MAP sensor, cleaned oxygen sensor. Also changed coil pac and ignition module. Car will now stsrt and run very rough for 5 to 30 sec. Then once in a while after several trys will start and idle perfect with good throttle response for 30 t0 40 min then suddenly start idling rough and quit, then back to the start, rough idle cycle. Sure could use some input. Before this problem the car ran great. Have owned it since 1990.
have the same problem?
