While replacing valve stem seals & rebuilding, compression test was done & also fuel pressure. If it is fuel-pressure, the idle would be rough, but this isn't the case. Electric voltage was also measured on the injectors & are within range. My question is (as I mentioned earlier), why one spark plug shows little more worn off than the rest. Could it be one injector is bad?
have the same problem?
