From experience it is a good idea to change both right and left bank O2 sensors at the same time. If not they might not sync up together and cause the check engine light to come on. The only way to verify is to datalog the sensors and overlay the two recorded signals.
What kind of fuel milage are you seeing? Did it get worse with the issue?
Good Luck!

My experience was with a mustang with less than 4000 miles. Trust me I was pulling my hair out trying to diagnose the issue. Then a Tech told me about this being a possibility and I did not belive it myself until I changed both at the same time and what do you know it worked.
Anyway good luck to the OP on getting this issue fixed.

Truck going back to dealer Monday morning, engine seem's OK and running smooth but the check engine light is staying on. 3300 miles on it so far and this will be the 5th trip back for this problem.

At this point your already meet the criteria of Louisiana Lemon Law especially considering a check engine light automatically disqualifies you from passing any federal emissions test. At this point you are in a real strong position to expect 100% resolution at your next dealer visit.

^^^x2 Good point Loki. I didn't even think of that. I wouldn't be surprised if they hold your truck for a couple of days and bring in someone "specialized" to help with this problem. The last thing they want is for you to turn the truck back in and lose a customer. Like Loki said, expect great customer service and a resolution to this issue.

Picked up the truck about 45 min. ago from the dealer. Total of 4 injector's changed and one HEGO sensor. Took it for a test ride and she's running great and no check engine light on. I then took her out to eat (Shell 87 octane) and came back home. Will give her a test tomorrow on my 100 mile commute!

Put about 60 miles since I picked up the truck yesterday and no check engine light came on. Engine running smoother and I got 17.6 mpg since filling up last night. I'll put another 60 heading home later after work. Now I can concentrate on doing more mod's!
