Check engine light came on, computer read code PO172. I had 2 new oxygen sensors put on, within 50 miles check engine light is back on. Any suggestions?

- I guess I should have mentioned: It is a new gas cap. I don't fuel with truck running. I have had the check engine light reset 3 times and continues to come on. 2 times before the new sensors and now 1 time since the new sensors. My concern is doing damage to any part of the truck that will shorten it's life or cost me more money later.

- I will check oil level again and let you know, thanks.
check your gas cap. If you fill your gas while the vehicle is running, it will also cause your light to come on. Go to OReilys or Autozone and they will shut it off for free and tell you the problem

Speedometer is erratic and engine stalls. Speedometer goes up to 120 mph even in part. When this happens, the engine bogs down to where it feels like a transmission issue but isn't.
