I have a hatch with a z6/y8 combo still running obd-0. Earlier this week it began running really rough including the idle dropping to around 500ish. After driving around for a while the CEL came on with a code 1 for 02, I replaced it as well as the spark plugs and it was still the same. I checked the new plugs and they are already black with fuel. The compression is all still around 210 and I even put on a different distributor, still the same. What should I be checking next? It seems like the engine is running incredibly rich to the point that it is running like crap. Any help is super.

 

were all of your spark plugs fouled?

Check that and then let us know...we need more details

 

Yeah all the plugs were pretty bad, and now the new ones are coated bad too. Im getting either too much fuel in there, or extremely little spark.

 

do you have a fpr or fuel pressure gauge by any chance?

 

I have the stock FPR, and nothing else, Im gonna end up at the junk yard this week and will grab some injectors and a fpr, is there anything else that might be causing an extremely rich mix?
