also ran additive.. running rough
Hi... I've been hanging around for about a month already.... new user... I'm from Guam and was referred to this site from a couple of friends. I have a 1994 MB C280 (W202) that I put some fuel injector cleaner in... it's been running pretty rough since after I put it in. I've already replaced wires and sparkplugs. What sort of tuning must be done in order to get the engine purring like new again?
