something is wrong on one of your banks, one is running leaner than the other, possibly a bad or slow o2 sensor or an exhaust leak. it is hard to tell what one is messed up, but id look for the slower switching of the two first.. jes

Cool,i learned something already.

#2 and #4 have the sims...

o2 sensor #1....rich-lean.475 v...Lean-rich.475 v low voltage switch .300/high voltage .600 v...rich lean time .048/lean-rich time.024

o2 sensor #3...rich-lean .475 v ...Lean-rich .475 v..low voltage switch .300 v/high voltage .600...Rich lean switch time .044 seconds...Lean-rich switch time .020...

Are those switch times okay? Mahalo man..




All times are GMT -5. The time now is 01:43 PM.
