Is the PROM replaceable on a 95 gmc c1500 there is no carrier and the legs look to be 1 piece that wrap under the chip? The computer is a BJLX if it matters?
I have a 95 305 v8 with a true dual exhaust with shorty headers no cats. And no O2 sensor. At idle the truck smells rich and the plugs after idling a bit are wet. Should i add an O2 sensor?
