I am back to thinking its the Fuel system. This morning car started immediately on first try. Stopped at store 20 min later. Tried to start car took 4 attempts all dash lights on in start position. Once it started I had to keep idle at 1000 rpm – if I let go of pedal the car would stall = idle dropped to zero. Did this for about 5 minutes driving in town. Engine then idled properly. Thoughts?
