still running too rich,low idle, smoking because of it

Can anyone offer a solution to my problem? 94 4.0. Only had it a couple of months. Only has 143k on it. Have new wires, plugs air filter, cleaned MAF, check engine light stopped working therefore ODB COMPUTER won't pick up any codes. I'm lost as to a solution. Don't have the time or money to fix right now,but need a solution instead of taking to a shop and getting ripped off. I'm a dyi'er. Want to fix myself if possible. Just don't have much time working six days a week.

rough idle/ slight miss

clogged fuel injector?

It would be easier for you to try to keep all of your questions, along with what you have already tried, what hasn't worked, and all of that in one thread instead of having 6 threads asking the same questions. Have you tried all of the stuff suggested in your other posts? If not.. why not?

RonD is a pretty smart guy.. start where he tells you, and he will gladly and in great detail walk you through some diagnostic steps. He's already started helping.. but you haven't indicated where you are in the process of trying out his suggested solutions.
