I did a few river crossings in my 1984 sierra and one of the last crossings the engine started missing obviously because water had got on the ignition system... After I sprayed the s#*t out of the ignition system with CRC it cleared up. Now sometimes under load the headlights and the front indicators only come on and make the engine idle lower and under acceleration the ignition just cut out and engine stalls.
When the engine is switched off and i operate the light they all work as they should...
There is no charge light on dash and alternator is charging...
What could my problem be???
