My car would stall on rough idol. I had lots work done to it like it has loose ground wire or short or wired wrong. Light dim at night hardly see road. Afraid vehicle stall and get run over. This was cutting car off faulty oil sending unit

Update from May 6, 2019: Yes the solution to this car cutting off in traffic has been found in December 2018 Out driving car to Wendy’s about 6 miles from my house. As noted many many times be fore at red light cut off. This time was different oils pressure I HHT come on in red. Oil pressure dropped from 40 to zero. Pulled over Wendy lot waked 40 minutes check oil. None on stick. Called Firestone. Car drove there. It had about 5 qts left in it On exam Firestone noticed beholden oil sending unit was leaking oil all oil drained out and new oil sending unit replaced. Car has not cut off one time since. Car had so many things done to it prior to them finding it. Such as fuel throttle replaced and sensor. All new plugs and coils air temp sensor cam sensor Varisble cam sensor new power steering pump. Idle pulley tension pulley shocks brakes battery power steering belt. I can go on on. That’s it

Update from Jun 1, 2022: The car continued to cut off for many years in middle of highway at red light, drive through. One day it cut off in Dec 2020 in middle highway It crank back up . Pulled into lot at restaurant I check oil None on stick called firestone. Told bring it right over. The oil checked and drained out on 4 quarts Vehicle hold 7 quarts They check around oil sending unit They noted oil leaking off of it. They put new one in cgange the oil. You need drive it about 40 miles at about 55 miles an hour so computer adjust to new unit It cut off once. It never cut off again I did put new alternator on it as it was not charginh right Runs better my new car.
