Ls430 misfiring after lengthy maintenance
I am STRUGGLING!! ADVICE NEEDED.
I have changed all the coils , spark plugs , fuel injectors , valve cover gaskets , intake manifold gasket, vvt solenoids a few hoses and oil change as well as compression check on the valves . I don稚 know why I知 receiving misfiring. The scanner said misfire in cylinder 1and 7 but keeps bouncing back and forth . I don稚 know what else to suspect the sluggish acceleration or the loud sound acceleration from the muffler system . I have been trying to pinpoint this problem for almost 3 weeks now and after changing all these parts I am now here please give me some advice and maybe any experiences you have faced with this problem I own a 2001 ls430 UL Modle with about 190k miles I have been suspecting the 02 sensors since none had been changed since I have owned the car and I doubt it had ever been changed but I知 thinking maybe new 02 sensors and catalytic converters or even just gutting and cleaning sensors . I知 not sure what else needs to be done but I知 open to all suggestions PLEASEEE.
