I tend to be pretty good at diagnosing. It's because I take the time to read up on the code etc and see how the engineers made it interact with other things. Learned a lot of very interesting things over the years and I'd never have thought X and Y act together like they do.
Want to solve this? Go get the info I suggested. Do your research and learn about the issue instead of guessing that it's not fuel related etc. I'm changing my tactics from me doing all the work to having the member with the problem do a certain amount of the legwork. We are here to help, not do all the work.
