Maybe my first post wasn't clear. The O2 sensor should at all times be in the 50-950mV range and switching fast back and forth across the 450mV cross count threshold. Only during warm up, at WOT and during fuel cut off it will be linear and not add to the cross counts. Idle was always most affected, when the O2 sensor was on it's way out. I am still pretty certain, replacing the O2 will cure the condition. We'll find out soon, I guess. |
