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????
