in the last few days have noticed it hesitates on takeoff with very little throttle. as soon as i press the gas ,it is ok. have also been getting code po-132.replaced the uptream 02 sensor with a bosch. can anyone help?
welcome... Normally I would ask when were the spark plugs changed last and have you cleaned the TB. But with the code I would inspect the O2s wiring /plug. Clear the code. If the code comes back change the O2s.
changed the plugs 5,000 miles ago with cheap ones. whats the best plug to use? also, no code yet but it has come up a few times so far.i have read on the net that bosch 02 sensors are not good to use on these trucks and to only use ones from the dealer- true or false?
That's a high voltage code. Disconnect the O2 sebsor and check the trucks power supply. Using the 02 sebsor wires as a corresponding grid check the truck for 12 v on the 2 white or black wires the truck plug would go into and .4-.9 on the blue and black/white wires.
NTK is our stock sensor manufacturer. You can get them fairly cheap @ RockAuto. They are exact replacements
