The pin, though, is adjusted all the way in (I had to put it in that far to stop the shakes). A mechanic that I mentioned that to told me because I had to put it all the way in, that might be a sign that my injection pump is going bad.

Now I am really worried. Is this surging at just below full operating temperature a sign that my injection pump is wearing out?

Thanks,
