to much fuel and back fires
Ok I put a cam in my car. I had the computer done by texas speed. I have headers and air lid stuff like that. Well started it up and it idels fine but when driving it it breaks up and back fires when giving it gas. the plugs are really black and you can see the raw fuel coming out. I change the map sencer and check the air mass. What could be causing this.

I am in Altoona. No there the same injectors. Yeah I got a ses light had a cheep scaner do a scan and it said it was the map or air mass senser but put a new map in and the tried the stock air mass still same thing. Could the O2s do this.

To Me, it sounds like they cranked up your fuel scales to high, but it could be a number of things... Maybe swap a stock MAF with a buddy, to see if that's the problem.
I use to have TSP tune mine, years ago, and I bought a spare ecm, so my car didn't have down time. Now, I use HP Tuners... You can even e-mail your tunes...

Bad 02s can really cripple your performance. It might be a good idea to get a set of new ones and try it. Usually you get a code for the 02s, but its worth a try to swap them.

I had back firing when I installed my headers and I tryed everything to try and fix it..... It ended up being when I installed the headers I just barly cracked a spark plug and that was causing the back firing and shitty running.
