Reset PCM to learn new o2??? Replaced o2 sensors today (BOSCH 13111)... SES light went off and then came back on... car has been tuned... noticed a HUGE difference in the idle after replacing them...
My questions is it a requirement to to pull some fuses/unplug battery and reset the PCM for the SES light and PCM to rest inorder to learn the new o2?

MIght help for sure if the old ones were faulty your trims could be way off. Definately do the reset.
You might want to check what the new code is for and reset all codes too.

I ended up pulling the fuse... un plugging the battery and letting it sit about 30 mins... after hooking everything back up... I tried starting it twice... on the third fire it fired right up with no hesitation what so ever and no light... Didnt get to drive it so Im hoping when I take it tomorow everything works out.
