LT1 Ghost...I Guess..... it seems like everytime i fix something on my car something else ***** up lol.
what would make my 96 z28 o2's read like .02volts and not fluctuate and have my short term fuel trim at 9.3percent on both banks.long term at 0. i installed new o2's again and reset the pcm but its still the same. my map is at 70kpa maf at 10. the car is thinking its lean and loading up with fuel.i have absolutely no exhaust leaks...and this is something that just started since i got it back running...but its been down about 3 weeks

k..finally found my fitting and checked pressure,,it has about 40psi at idle with vacuum. when i remove vacuum it jumps to about 45psi.and at idle the engine is kind of stumbling.i pulled about 4 of my plugs ...still look new.so as of now it seems that im not getting enough fuel yet i have good pressure.not black and fouled like i was thinking they would be. i replace the fuel filter about a week before my opti died
