Current milage 145,000… Engine lite on going to shop on the 10th… Getting strong smell of gas / rotten eggs… I believe it is the O2 sensor… I hope it is not the Cat…
mattdupe,
Have your car’s codes scanned at Autozone or Advance for free and post the code(s) back here in number form like: PO123, etc.
Maybe somebody can give you a heads-up.
How about engine size? Post that, too.
