2003 1500 with a hemi. It is the upstream O2 sensor. Even with a new o2 sensor the damn thing keeps popping up. Also the darn idle keeps surging when the engine light comes up with the code. Have new plugs in it and the old one looked good. |

Quoted: You need to check the wires to make sure there isn't a break or corrosion. If the wires are good it probably has a intake leak or bad iac valve. Wires are good. Have spayed all around the intakes with starting fluid and nothing happens. Quoted: Is there 2 upstream O2 sensors? 1 for each bank. Did you replace the correct bank if there is? There is only 1 upstream on the 03 and 1 after the cat. |

I just had this happen on a 98 Caravan. That code for the Caravan was supposed to indicate a problem with the throttle position sensor. I was also experiencing the same symptoms. Most of the online references said to check the harness that led up to the sensor. I peeled all the tape/loom off the harness. I found lots of wires that were starting to fuse together. I separated them all, re-wrapped the harness, and all is good now. |

Ran like it was loading up and than the throttle would have a big delay in it. Never happened before this though. |

I am stuck working on it for him. Fords I have this one.   Also a 97 F350 with the 460.  |

Hopefully you've bred the dodge gene out of the bloodline.
