Ok so my car has been running ruff so I took the plugs out to check them and they a covered in black soot. I have a 255 pump with afpr set at 41 psi at idel, with stock black top injector. The rear o2 is not hooked up to the eexhaut but is just straped to the under carriage, would this cause the problme or what else should I look for?
