Oh no....a new issue for my tb45e. Where to look?

[lhurley]

So I woke up and started thinking. The power is only totally down and erratic when at idle and coming up to speed. Could this maybe eliminate vacuum lines as the miss seems to disappear higher in the rev range? Would/could the symptoms be associated with spark plugs and leads?

Nah plugs and leads would be consistent if not worse at higher revs. I think evo might be on to something with the running both fuels. If that was the gas it would run like a pig in low revs as it's running to rich, but be some what better at higher revs and it requires more fuel then and could be leaning out a bit/enough to seem ok.

Do you have a snorkel?
