miss fire questions
i got 99 t/a full bolt on's i hit the car with spray not too long ago, and now im getting p0300 miss fire code. car misses at idle and part throttle cruising i get on the gas a lil and it goes away.
looked at spark plugs and they look ok, changed the wires don't know what else to look at they say weak fuel pump can cause this or fuel regulator ? what about fuel filter ? i doubt its a coil or injector cus the miss is all over the place looked at live data and i got all 8 missing. if it would be a coil or injector it would be one 1 or 2 right ?
need some help car sounds like **** and its chugging gas like never before.
thanks in advanced

Im on the mobile site so I cant see your sig. Does the car still have cats? If it does one of them could be clogged. Is the nitrous dry/wet and how big of a shot are you spraying. What plugs are you using? I'm just gonna guess and say your 02 sensors are screwed up. I've heard and experienced that N2O tends to wear them out pretty quick especially if your tune is on the rich side of things.

thanks so that's most probably whats going on then. i was a lil worried cuz to tell u the truth i was trying to blow the motor that night. cuz of my uncle told me if i blew it he was getting me a 6.0. i ran it with the predator tuner with timing advanced and leaned out and no boom. i did have a richer fuel side im going to try on my brothers o2s and see if it gets better thanks for the help.
