Throwing codes
My '96 4.9L keeps throwing the following codes: P1151, P0174 and P0153.
I changed the O2 sensor between the cats and reset the computer; the truck ran fine for about a week and now it's throwing the same codes. Once the CEL came on and then went off about two hours later. I checked the computer and it had the above codes in memory.
The truck is all stock; except, I took out the filter box and installed a K&N filter kit.
Any ideas?
Thanks for any help.
