I have a 2000 f150 6 cyl. and She started missing at high speed and now she is dying when i slow down to turn. CEL came on and is giving me P1127, 1132, 1152 and 1158. I have changed the fuel filter and cleaned the MAF sensor. Any other advise would be appreciated.

LXman, the truck is a 4.2L V-6. That TSB refers to 4.6 and 5.4L V-8 engines only. I suspect an O2 sensor wire damaged.

 

OOOPs, you are correct. Could be either a bad O2 sensor or wire somewhere.

It could also just be running so lean that it can't compensate for the lean condition. I would check all of the vacuum lines, especially the PCV hose elbows, for a vacuum leak.

 

If you look up the code discriptions, you will see the 1127 code is telling you there is a temperature problem. All the rest of the codes are reporting the same fault with differnt code#.
Question; is there a fault in the heater circuit of an Ox sensor, Is the sensor faulty etc.
A lean reference for the codes is to the fuel tables going to their lean setting as a short term fuel trim condition trying to correct for a rich condition.
It may or may not be an air leak at the inlet tract considering there is a 1127 code along with the others.

 

I have read where the lean condition did cause The fuel table codes, but I am still thinking bad O2 sensor.

 

There seems to be a common culprit in these replies. I am going to replace the o2 sensors and see where that gets me. I will let you know how it goes. Thanks for taking the time to reply, it is greatly appreciated.
