Hope this is the right thread. I have had a chronic problem of frying my O2's since I installed my LT's. I am on set #3 and its maybe 3000 miles since the install. I am using the Bosch O2's for the vetts with the longer cord. I am also running sims for the downstream O2's. I have been told a tune would cure it.

My question is
1) Anybody had this bad a problem
2) How would a tune fix this.

BTW, the codes thrown were

Slow switching for Banks 1&2 Sensor 1. and one other related code that I cannot remember.

Why am I concenred now? The auto parts store will not warranty them anymore!!!!!!!!!

It's a fairly common problem.

Take a gander at this thread and my saga with o2's.

On the last page of the thread one of our respected members reported to have cured one guys o2 problem by simply replacing the Bosch 13111 with a stock sensor.
