Greetings Peter.

I was told as well that the camshaft may be my problem, but that would
mean a constant irregular idle or in my case a miss in the firing. My
problem is an intermittent miss and intermittant poor idle. Sometimes I
can drive for a couple of hours before this roughness starts. Especially
when the engine is hot and driven hard. (Coastal mountains) Another
strange symptom I have noticed; sometimes when I corner hard, a tight
righthand sweeper as in an onramp to the freeway, the engine smooths out
nicely.
Thinking seriously about a swap like David Marshalls. Been messing
around too long on this powerplant.
