My oxygen sensor is less than a year old, and the box was reset at that
time. I have the old one and it will be installed to see if that makes a
difference, I'll also be replacing the Temp 2 sensor....again. But, for the
most part it seems like the two of those are NOT the cause. My ground straps
have been replaced and every wire has been checked for resistance. All the
mean while, the engine runs absolutely horribly until fully warm, even then
the idle is a tiny bit off. A major vaccuum leak seems to be suspect, yet
that wouldnt let the engine run so well when warm or at higher RPMS. I'm
very confused.
I think my engine's thrown it's "Johnson Rod"
