Hey Scotty: I have 07 Explorer Sport Trac 4wd, auto with 150k. I've got error codes P0135 — O2 sensor, P0141 —- O2 sensor, P0155 —- O2 sensor, P0161 —- O2 sensor, P0403 —- EGR Valve, P0443— Purge Solenoid. Replaced purge solenoid as it was the least expensive. Any help would be much appreciated. Thanks Ron

This is most likely a clogged catalytic converter due to long oil change intervals. Is it running rough?
