K...changed out the oxygen sensor under the driver side........the only codes showing now are :
P0122 TPS low input
P0405 EGR flow sensor input
P0452 EVAP emission sensor low control
I also changed out the fuel filter.....which was pretty clogged.
The SUV still drives the same.....slightly better.......but not well enough......however....we noticed that when revving the engine and unplugging the harness from the map sensor the engine operates normally....no sputtering or stalling.
Could it be the MAP sensor or something else that sends info to the map sensor?
Thanks
