The Service Engine Soon light cam on, so I hooked it up to a diagnostic scanner, which showed code P0300 "random/multiple cylinder misfire detected". I have replaced the fuel filter and spark plugs (the center electrodes were pretty worn, but all cylinders looked like they were burning good), but the problem still persists. I don't see any vacuum or other hoses unhooked or cracked. The symptoms seem to be similar to a choke malfunction on a carburated engine. Any thoughts?
have the same problem?
