C'mon now, YOur engine requries some servicing. It is HIGHER mileage, right, and some things are a GIVEN at 100k miles. You are going about this the WRONG WAY for the most part, You should be checking the POWER SUPPLY at the wiring harnesses. OLDER O2 sensors were simpler, They had NO heaters in them yours DOES so get NEW ONES from either BOSCH or NTK.AFter about 100k miles the HEARERS on oxygen sensors tend to wear out. FIRST OF ALL have your THROTTLE BODY and IDLE AIR CONTROLV AVLE cleaned up to SHWOROOM clean. This is WHAT the O2 sensors ADJUST! THE AIR supply to the engine, not the FUEL part. The IAC adds more AIR to the injected fuel as it enters the engine. BAD wiring is a REAL possibility as your O2 sensors lie UNDER the truck and are exposed to LOTS of road salt. This is a REAL problem as time goes by. You can TEST the wiring harnesses for continuity and more, like RESISTANCES. ROAD slat can RUIN the wiring and even the conectors. ANYWYAS once yoru T body and IAC are TOTALLY CLEANED UP, the fuel will METER correctly and your O2 sensors JUST might JOLT themsleves back into working right. But once the HEATERS go bad or the harness gets gummed up with AGE and ROAD SALT, you have to start expecting to pay for some attention. AN electrical shop can be helpful, or the use of a VOLT OHMETER on the harnesses would ALSO be helpful GOOD LUCK TO YOU and E mail me BACK with your resutls. GOOD LUCK
