Sounds like the pre-CAT O2 sensor is reading incorect. It might have a coating of mineral or crap on it giving the incorrect reading and triggering the code or the harness is wet. Get some SeaFoam and litely drizzle it down the TB at about 2k-3k rpm to clean out the CAT before you plug it if you haven't already.

Then replace the pre-CAT O2. Finish with a reset and clean a little more then a possible 2nd reset.


Lastly it could be the MAP sensor triggering the issue.

 

too late i cut the cat and straight piped it didnt help still 6 miles to the gallon at65 on criuse control sounds sweat though
