Fuel injectors
NEED SOME HELP. I'm really new at all this researching and learning as I go. 1990 vette with stock L98 TPI. New Battery, Altenator upgrade from 105 to 124 volts. The cars inside and outside lights continue to flicker too much, and the Battery meter reacts a lot. Example: everytime I use my turn signal the lights dim and the battery volts lower at the same turn signal rate. I've never had issues with the car in the past year since I got it. Car has 120,000 miles. The service engine light comes on just about everytime I drive it about 2 or 3 times a week. I turn the car off and the service engine light goes away. Today the car suddenly shut down on me while idling. Turned it on worked fine for about an hour. On the way home it almost shut down again and barely made it home. Battery and Alternator test is good. Tested the fuel injectors. All reading a consistent 19.4 ohms. Not sure what the injectors should be reading.

You may have a loose ground, also there is a terminal block behind the battery. Check those terminations and clean if necessary. I also believe there might be a TSB for wires chafing at the transmission and block on 1990's
