thanks for the suggestions. A question about the knock sensor--would it start pulling timing boost right away? i would think (and I could be completely wrong) that it would allow full boost and then go 'whoa' when it saw something it didn't like.

Keith--the plugs, cap and rotor were changed last fall (15 months ago). They're on the list to check, as well. Would poor spark lead to low boost? Again, I'm just asking.

Thanks

Doug
