ok.... so my son's first car a 1984 fiero 4 cylinder automatic
has developed a stalling issue, after 7 months of problem free driving. . It can stall at any time, cold or hot, wet or dry, idling in park or in gear or running at 80 kph. it could run great for 3 days but on the forth it could stall 5 times in 10 klm. Sometimes it will start again after a few min and sometimes wont start till next day. When running, its smooth no erratic rpms no check engine light or codes took it to 2 mechanics they can find anything wrong with it, one mechanic had it for 4 days and used it for part pickups and it never stalled, he even mention how well it ran. When I picked it up it stalled 500 feet out of his driveway and would not restart and we pushed it back. We replaced, fuel mapping sensor, coil pack, distributor,, plugs, wires, all filters ran it for two days no issues. My son came to pick it up and it left him on the side of the rd 12klm from the shop.
So now he doesn't want to drive it because it will leave him stranded some where. And he cannot afford to keep throwing parts into in for trial and error purposes.
Any help on this would be greatly appreciated.
