[V8] TPS & Not-so-smooth Engine

[Tony and Lillie]

On an automatic car, the TPS is only used for transmission functions, other 
than full throttle and idle signals.

The first things I'd check are the connections on the TPS, MAF, and unplug 
teh O2 sensor, and see what, if anything, changes. If you do end up needing 
a TPS, I'd suspect Ron may very well have one, and I may if I do some 
digging for that matter.
