[V8] problems solved.....well, SOME of them

[Dave Saad]

It might just be the exhaust pipes hitting on the cross member. when the motor mounts start to collapse, this happens. One way to tell - look at the front vibration mount at the front right of the motor (by the alternator). if it is broken (it will have a large gap because it is broken in half) then this is the problem.
The top bolt of the mount is easily accessible. 
Removing the cross member is also easy. You could do that and see if the noise goes away.

I thought it might be a fouled plug and was all set to rip out the plugs and replace them. But the plugs aren't very old and were the correct Bosch plugs so I was a bit reluctant to do anything especially since the car was scheduled to go to the wrench for tires and a new inspection sticker in early May.  So the car went and after a bit the trouble with the roughness was located. One distributor cap was cracked. Now that makes me really pissed because both caps are quite new...as in less than 45,000 miles...but now with the cap replaced the car SINGS!

That's a thirty mile drive entirely on two lane, rural, hilly and twisty roads.  The vast majority of the time I encounter at most half a dozen other cars going either way the entire distance.  One of the roads that is wonderfully hilly has been freshly paved. The V8 LOVES that stretch!

Tested and found the sending unit was getting signal so the only thing left is something annoying in the cluster.  For now I am not spending ten cents to chase the phantom.

At first I thought it might be the half-shaft as it seemed to do it mostly when I turned left.  But several times I have experienced the sensation....it's a sort of shudder...upon acceleration going straight ahead.  It all appears when the car is in certain attitudes, such as steep climbing from a stop sign, then I feel this shudder in the rear.  I am worried it might be the torsen differential clutches or some draconian evil lurking back there. For now my plan is to go carefully and next spring when the car goes back to the wrench for it's inspection sticker, we'll chase that one.  Assuming it doesn't just stop someplace and leave me walking!
