Hello all,
After a break of six months or so, I am back and preparing to work on our gmc again since the snow will be gone soon.
Last fall, I had a new timing chain installed on my coach. Thanks to Bruce Hart's efforts and instruction, we were able to diagnose the problem and teach me something at the same time. Since I am a coach-net member, I was able to get them to tow the vehicle 80 miles to the nearest "GMC" repair facility. Once the chain was replaced I was able to drive it back to my place. Well, nearly back to my place. I live in the foothills of Colorado at 8400 feet elevation. My coach died one mile from my place from what I assume was vapor lock. I let it sit and cool for a couple hours then was able to continue up the hill to my driveway where I couldn't get it to go another foot. The bottom of my driveway is at 8272 feet while my house and shop are 800 feet away at 8426 feet....Ugh. It has been sitting there over the winter.
My plan is to install an EFI unit this spring in an effort to allow us to go over mountain passes that are a good bit higher than 8400 feet. I've been told that the EFI should enable us to do that. Thoughts?
Also, when I got to my driveway, the engine was running but I was barely moving. How can I tell if the issue is engine related or transmission related? What I mean is that I don't know how to tell if the engine just wasn't getting enough O2 to drive the vehicle, or if the transmission wasn't up to the task.
As usual, thanks in advance, I always learn something from you all, so I am ready to be taught!
