Hello Fellow Pre-1997 F150er’s

I am new to the community and I just bought a 1995 F150 XLT Supercab 4x4 5.0L AUTO & MANUAL SHIFT TRANSFER CASE with 8FT BOX.
The truck has 263000 miles and she needs a lot of love all over. I would like to use this post to track all the improvements and welcome your thoughts along the way.

A little back story, my first truck was a 1995 F150 XL 2WD 4.9L AUTO 8FT BOX and it was the best vehicle I ever owned.

So I am looking forward to bring this old 1995 back to life.

Thanks.

Bob

 

Welcome! post up a pic so we know what your project looks like.

 

I have put less than 1k miles on the truck and getting a rough idle condition when the truck is warm. When the engine is cold, start the engine and let it idle and drive it until it warms-up. Everything is fine. Turn-off the engine, restart and the idle is rough spikes between 500-1200 RPM and sometimes stalls.

I have an OBD SCAN tool and ran the following two tests:

KOEO

Emission Status Yellow

DTC:111 (system pass)
DTC:172 (HEGO (HO2S) sensor fault/lean) (now need to check which: fault or lean?)

KOER

Emission Status Red

Cylinder #8
DTC:411 (I need to look up)
DTC:538 (I need to look up)
DTC:536 (I need to look up)
DTC:632 (I need to look up)


Please note: I put a new CAT back exhaust system when I first bought the truck and noticed that tube between CATs was rusted, busted off. So the tube is sucking clean air vs. exhaust gas.

that could be your issue. fix the tube and you should be able to fix your idle surge.
