So I was coming from my girl's house and all of a sudden the car started driving like crap. It had horrible gas mileage, black smoke and started misfiring. I checked my knock sensor..... I run without one. I got a new MAF sensor and that car was still idling rough, stalling, had bad gas mileage and all that. I don't have any vacuum leaks and my O2 sensor is good too. I am running forged internals stage 2 camms port and polished head new valves and valve springs distributor good along with spark plugs.

What's next? Is it the Camshaft position sensor crankshaft postion sensor? I run with Apexi neo .....pieces of shit, so I don't throw codes and my laptop is down so I can`t sync into my ecu. need help.
