Hello everybody, I am new to the forum and am excited to be a part of this online community. I am fairly new to GM cars in general, however I am not new to cars by any means. I also have a pretty heavily modified 1969 Mustang and have a decent amount of experience working on a lot of types of cars. I am the proud owner of a 1982 Cutlass Cruiser and have already done the s10 brake swap with stainless lines, changed the front and rear springs (slightly stiffer up front and CC's in back), and I am still catching up on fixing some of the things that were wrong with the car when I inherited it (thank you grandma!). She isn't a lot to look at and she has some rust but I am ok with a car that doesn't look perfect. After some of the issues are sorted out I will definitely install a rear sway bar as the body roll is still pretty bad after the stiffer springs and poly endlinks and bushings up front.
I have the car driving pretty damn well and have had the factory electronic carb rebuilt. I recently had the alignment done, and shortly after I got a check engine light. I used the testing process to get a code 13 for the o2 sensor. This was definitely the problem as the harness side of the connector was ripped from the harness wiring. This is one of many reasons I never trust shops and expect they will mess something up. The control arm shaft cover is right by this and I am sure the shop broke the wire. Here is where I feel stupid.
The wiring diagrams I have seen show that the wire for the o2 is purple (correct) and eventually connects directly to the ECM. The factory wiring looms and even factory zip ties are all intact, this car was garaged for half its life so all the wiring stuff is in pretty dang good shape. I looked everywhere for a broken wire on the harness side and could not find anything. Is this wire still purple on the harness side? Which loom should this be in and what other color wires are its neighbors in the loom? I gotta say I feel stupid asking but hey not here to impress anyone. The diagram shows a direct connection to ecm and its labeled purple but I wanted to be sure it doesn't change colors after the connector.
Looking forward to "meeting" everyone and I hope you bare with me as this is my first GM car.
