I was throwint two codes. Bank 1 sensor 1 and the precat sensor. Did the light come one the first time you hammered on it after the tune was installed? I got another tune and the problem went away. Perhaps you got my old PCM. LOL.

I have had it happen with two PCMs now. I think I am going to just buy two new sensors and get $20 worth of free gas!
Look Here!

How much are those sensors? Why not just get the original factory ones?

FINALLY got new o2s. I went with Bosch 13026. No SES lights on the first test drive last night and they are acctually reading! Started it up this morning and felt a hesitation and BAM SES light. Both sides threw a code. Something about the heat thing! I have stock manifolds, WTF! Do I need differant sensors? It has only happened once and I have only started the truck 4 times and on all start ups I have let it warm up. I have no lights now since i cleared them on the third start up and my plug replacement. Let see what happens! You think I will throw the code again?

There is a good chance no matter where you guy your sensor, it will be the same part, so go for the cheapest buy!
