We need the trouble code number to be of real help.

But, from the stand point of the HO2S sensor, if that is indeed the fault, then letting a bad HO2S sensor go and not repair the problem, can lead to a lean condition.
Lean conditions can lead to burnt valves, burnt pistons and overheating.
So it is often in your best interest to repair cat efficiency faults.

supply the trouble code and we can look more indepth into where the problem may be.
