well the 4.0 has a misfire again and its starting to act like it did the last time when the heads were replaced.. it shakes at idle and when you have the cruise set it will just randomly buck.. hooked up mac mentor to it, and it says misfire cylinder 4 and o2 sensor codes (rich and lean on same one)
here's whats been replaced. (all within past 6 months)
heads, head gaskets, head bolts, plugs, wires, air filter, fuel filter, maf cleaned, tb cleaned, o2 sensor, one injector( cylinder 4). new valve cover gaskets and uim gasket,
its a 99 4.0 auto 4x4
