[V8] V8 suddenly running like a coffee grinder above 1700 rpm

[dsaad at icehouse.net]

Once you rule out all the usuall sensors and fuel related issues, you might 
want to have a look at the ring gear teeth. I recall someone recently who had a 
car that would not run over about 2000 RPM and it turned out to be missing 
teeth which messed up the timing sensor. Hope that is not the case for you.
