i have a little issue with my engine. Cylinder #4 seems to have a misfire or not working period. I checked for spark and it has plenty. I checked the injectors , even swapped one out from a good cylinder, and still same thing. My UEGO tells me im running lean, but thats only when idling,that could be due to maybe having no fuel on the fourth cylinder of course. However, when driving it actually runs rich. I know that b/c i can see the black smoke out of my tailpipes. I also checked the plugs and they were pretty black. I have a completely stock engine for the moment, and cant figure out why the #4 cylinder is faulty. Can it be that maybe the #4 injectors resistor isn't working , therefore causing the misfire? Any suggestions, Im trying to do all the little stuff b4 i go opening the engine up.
Thanks
