hello all...p0133...got this code up : 02 sensor ckt slow response bank 1 sensor

p1131 as well...manufacture control fuel air metering...which i think is sensor as well....

truck runs...everyday 70 mph but at times when i slow down to 40 and then speed up "WITHOUT" heavy foot, it bogs a bit...chokes,then clears up and goes. its about 90% 60 or above mph to work 18 miles....i feel it. it bogs chokes then lets go.

so......change bank 1 sensor one ABOVE cat....? anyone do this? looks hard to reach...lQQking at it now,lol.

txs all

 

How old or how many miles are on the O2 sensors now ? A worn out O2 sensor will throw both those codes. The front sensors are a bitch. If you're replacing them with new ones you can just cut the old ones wires to make it a little easier to get out.
