I am having bosch sensors stop working after about a month of use . I just bought a zeitronix zt-3 wideband with the bosch sensor about 3 months ago and have gone through two sensors already . When I had my car tuned my tuner adjusted the a/f to about 11.7 at WOT on his wideband(mustangdyno) and my gauge didn't agree with that at all reading a 10.3 at WOT (when the gauge was working properly). It has since stopped working since yesterday and reads random numbers no matter what . What could cause them to stop working properly ?
I had the car on a dyno yesterday at a local car show(dynojet) and did two pulls and my wideband and the dynos wideband was spot on at 10.3 WOT . I am thinking that my car is running rich as there was some black smoke out of the tailpipes . The guy running the dyno said it was rich and that he could lean it out a bit and put some more numbers to the rear wheels no problem. If it is actually running that at WOT like my wideband and the dynojet shows, then it is certainly to rich for my liking . Could the unburnt fuel flowing through the exhaust be causing them to burn out ? The last one I pulled out of my x pipe was black as can be . Please let me know what you think in this matter . Looking for opinions and may take it to my tuner to have the tune adjusted . Thanks in advance .
