OK, I had a bad injector signal a while ago (94 V6) and had gas running out of the tailpipe! Anyway had all of the injectors and computer changed. I'm up for emissions and wasn't sure if it'll pass after all that raw gas going through it and my Check Engine light is on and nobody has been able to tell me why. Anyway, just looking ahead if I fail emissions, I see the pipe and converter assemblies online, but they look like they only have the back O2 sensors, not the two up by the exhaust manifold. Do I need all 4 02 sensors?

The engine has about 30K on a replacement long block and I've replaced the following;
computer
6 injectors,
MAF sensor
2 forward O2 sensors before flooding issue (didn't make the check engine light go out)

Any help would be appreciated. I really don't want to have to haul it to a shop again $$$$$

First step is to pull the codes to determine what is throwing a CEL.
