since i installed alky my idle is terrible after some hard use. when i install a bosch sensor after a while my o2's go in a lean condition at idle 400 to 550 fluctuating bad in a closed loop wot runs are not affected it runs great off idle and wot . i have a turbo tweak chip which it should go into a open loop and lock on to a number. well when i tap the test button on the alky the o2's lock on to 780 or so and the idle smooths out then when the alky is burned off it goes right back to the ****ty idle. then i install a new sensor and it runs perfect for a month or so. i am on my second one since MAY?????? are these sensitive to alky????alky and bosch o2's

I've had bad luck with everything besides a good old AC delco.
BAD LUCK With these so far:
Bosch
Denso
NAPA
Standard
None of these could take the heat / pressure in the stock location. They all tanked to 100mV when the car was running fat as a pig!

ummm....my money would be on the WBO2. Narrow band O2s suck. they have been documented as being "off". My very first experience with a WB was at a dyno. My "stock" O2 was reading ~780 MV - the WBO2 at the dyno was reading ~9:1 AFR. just "messing" around with fueling i INSTANTLY gained about 50rwhp. I havent had a chance to tune yet with my recently installed WBO2 but i love it and i highly recommend it over an EGT.
