Engine Performance problem
1990 Chevy Beretta 6 cyl Two Wheel Drive Automatic 260 th miles
Re: 1990 Chevy Berretta 3.1 liter
Oil pressure light on dash flashes with key turned on to alt. (Other idiot light just light up, they don’t flash like the oil pressure light.)
Throws a code 21 which has to do with an elevated TPS voltage relative to the air flow.
Single wire from alternator to positive on battery does not have continuity= probable bad fusable link.
I wired sinle wire directly to the positive on battery. Now alternator charges about 14.5 amps but car won’t rev up.(This is the original problem)
In other words when the alternator is not hooked up the car revs up and runs better.
Any ideas the car won’t rev up and run right?
