HELP! O2 Sensor Issue
Have a 2001 Durango 2wd with a 4.7 and 160,000 miles.
Original O2 sensors lasted 155,000+ miles.
Been through 6 since (5 up-stream and 1 down-stream) in the last 2 months. They seem to last about 2 weeks +/-.
No sign of external contamination that I can find.
Haven't done any engine work so, no possible contamination from silicone sealers.
Thought maybe a leaking headgasket and hence, possibly antifreeze contamination but, no change in coolant level.
I heard the after market ones were junk so, spent the $100 on the Mopar one and it lasted a shorter time than the Bosch ones from Autozone.
Any help would be appreciated!
