My car for the past couple weeks hasnt been itself lately.. I have new bkr7e plugs in that worked fine for a while set at 24thou... I just set them to that right now, have tried 30,28,26thou and hoping 24 will work better.. timing is at about 18deg.. it has ran fine for over a year now just until recently.. any thoughts as what might b the problem???
Also I have code 20, 36, and 41.. first 2 dont apply to my setup but 41 is new.. I dont have my check light on when I'm driving just curious if my o2 sensor is dying or something? could this cause a missfiring problem? the o2 sesnor I bought new last year..
