Black smoke blows out under WOT and normal drive. As of recent I have thrown codes for
Bank 1 sensor 1
Bank 2 sensor 1
Cyl 1 miss fire
O2 sensors stuck on rich
To fix this I have replaced all 4 of my O2's, Replaced all 8 spark plugs, all 8 coil packs, re-programmed with my hand held tuner to 0.00% richness, Installed a new MAF sensor and even dialed down my Kennebell Boost-A-Pump. Car ran great for a day and then the dreaded O2 codes came back. The car started popping/ detonating/ sputtering and black smoke came out the exhaust again. I do have a wet nitrous set up and have checked to see if fuel is leaking into the intake and it wasnt. I have spent over 100 dollars for a 1 day fix. What the hell is making the car run rich and foul out my O2's and spark plugs?
Is my next option to take it to a dyno shop and have them play with the computer? Ive ran my current tune for 5 years and it hasnt failed me before. Any ideas?
