Customer Question

My 1989 xjs seems to be running lean on the left bank, cat is getting Red hot

good afternoon my name is ***** ***** I will assist

the fact that the cat is red hot indicates that there is too much fuel in the exhaust indicating a rich running condition. if you have a miss fire from a bad plug, injector failure or a cylinder issue, that would explain the issue.

what has been done so far????
