There's a very good chance that the Bosch part is at fault here. They're known to be disliked most of the time by our trucks. NTK or Denso are the only ways to go with that specific part.

 

i heard ntk is good so i should go with the ntk then?

 

Yes go with ntk might just make your truck happy enough to run right

 

My truck is sporting a pair of NTK's and likes 'em fine.

 

I replaced both 02 sensors today with a pair of ntk's i disconnected the batt when i installed them and put some fuel system cleaner in it as well the check engine light went out so far but im still having the same issue there is a few things i noticed today the intake has been louder than normal and it likes to stay in higher gears when driving i pulled off the wire going to the coil and there was quite a bit of rust inside the wire and on the coil i cleaned the coil and got new plugs and wires today but haven't put them on yet but im running out of ideas if this doesn't work all thats left is the cap and rotor witch im going to replace tomorrow as well so hopefully this fixes it.......

 

Let us know how it turns out.

 

im starting to think it might have a bad vac leak i checked them but im going to go back threw them again because of it trying to stay in high gears when driving and when u press the gas slightly u can hear quite a bit of air
