alright guys here it is I repair one or more of these a week first few I had I also thought it was the tbody but one of them got me on day normally when replacing the t-body the engine harness gets moved around which can make it seem as though the vehicle has been repaired but it usually comes back to bite you in the backside
best suggestion remove the 10mm bolt that holds the engine harness down to the drivers side valve cover run the vehicle for about twenty minutes or untill the harness is nice and warm for once its warm its going to move easier
ok now that is warm pop the hood leave it running grab the harness near the hold down bracket where you removed the bolt pull twis and tug on that darn thing as hard as you can if the vehicle stumbles or dies out guess what its time to go swimming in the harness thats where it gets fun remove the wire loom as much as you can get to pull on each wire one at a time remember you are trying to get one of them to break but dont be a gorilla give the a good tug you may find one or more of the wires will break just solder them back together and you will be good to go
