Ive got a problem while toped in drive or reverse fine when in park and notrol. It has a rough idal doesnt die but when i go to go drives fine. Truck is great condition good gaskets and so on but error codes
Are #P1150 / #P0153 / P0171 . Please help the truck is to good and nice for it to run like that. Any thing would good thanks in advance

 

I understood the last sentence, - no idea on sentences #1 #2 and part (the beginning ) of #3. Are drunk ? High perhaps ? Well, I hope they weren't that important. Can anyone decipher those for me?

Anyway, -

P1150 Lack Of HO2S21 Switch - Adaptive Fuel At Limit.

In other words,- Switch Fuel Trim At Limit.

P1153 Bank 2 Fuel Control Shifted Lean (FAOSC).

In other words, -Heated Oxygen Sensor (HO2S) insufficient switching bank 2 sensor 1 (Front Bank)

Looks like you problems on both banks. Well the first two DTC's go together, they're for Bank two (drivers side). Prob a sensor malfunction, switch or switch circuit.

P0171 System Too Lean (Bank 1)

That could be a number of things, -

Dirty MAF
Vac leak downstream of the MAF.
Cracked vacuum or PCV line/connection.
Faulty or stuck PCV valve.
Failed or faulty O2 sensor
Sticky Injector
Fuel Pump (LP)
Exhaust leak, between bank 1 upstream O2 Sensor and manifold.
Intake manifold gasket..Bank one , = drivers side.

Have you done anything to harness or sensors, - get them wet or whatnot ? Check the harness for evidence of burning.

 

Sorry have spelling issues. It just has a rough ideal while in drive/reverse but park and N is fine. Doesn't die out just vibrates a little. It doesn't act up all the time. I've done new mass flow air sensor, got new cat converter with new studs was a little hole in manifold patched it up, I've done oxygen/O2 sensor on bank one sensor one (upstream). What else could i do.

 

Have you disconnected any other O2's from the harness. Once connectors are disconnected they always have to be cleaned with electrical well. The grease that the factory uses attracts dirt and dust when disconnected..quickly. The O2 signal wires (the black wires, - grey = ground with these 02's), well , -all terminal conductors need to be cleaned and flushed since they are so sensitive. Just disconnecting and reconnecting can cause issues...picky.

You should always change both upstream Bank 1 and 2 at the same time to keep system integrity at both banks. It's a better Idea to change all 4 to keep switching at it's best. Switching all 4 contributes to economy. Switching problems digs into your mpgs. This is the ONLY thing that rear O2's have to do with AF's..nothing else. Otherwise their just cat /efficiency checkers. Has to do with the HO2 monitor we use. The peak and low voltages are continuously monitored, but if the monitor has not detected a peak or low voltage beyond threshold, then the fuel/air mixture is forced high or low in order to get the sensors to start switching. If this sequence does not 'shock' the rear sensor(s) into switching, then a DTC is recorded BUT, - during and possible after this event, economy won't be the greatest. Changing all 4 has it's benefits...more than most may think.

At least change both upstream. That may not fix the PO171, but it should keep both upstreams working at the same level with each other.

Also, changing your fuel filter may be in order.
