The problem I'm having is that after about 2 weeks I get a pretty good buil-up of black soot coming out of my exhaust and sticking to my back bumper. I know this is probably a fuel problem, I'm thinking possibly injectors. I've tried fuel injector cleaner but it didn't do anything as far as I know. If it is injectors are they generally easy to get off and clean off a 4-banger? I also have white plugs, I think it's running lean/rich, one or the other but righ tnow I'd like my car to quit spitting black out the back. Thanks so much and sorry for posting here but everyone here is so much more helpful, and I am an old family member!
