So I have a 1991 mustang engine is all stock passes smog. I washed the engine then started the car up about 5 min. After washing it then moved it about 40 feet to dry car then started it up again 15 min later to leave it started good but then it just shutoff now it has a very hard start and it backfires bad when u give gas to quick if u accelarrate slow it is ok but can't let idle because it will die need to give it gas so it can stay on thoose are all the symptoms I'm getting right now. Oh and my cluster doesn't work oil temp voltage I'm thinking it is a fuse. And the alternator is charging. I'm thinking it could be the throttle POS. Sensor or mass air any responses would be very appreciated.

U might have gotten water in ur cap and maybe got water on the plugs too. Change them out

If you din't cover the elec wires and alternator,dis cap etc now you know I use aluminum foil works great. and try to avoid direct water to these parts.

Ive done the same thing , more likely than not you got water in the distributor . Take off the cap and rotor and blow the water out with an air compressor !

you got water in the test port located on the firewall or by the brakebooster!
