Ok, backwards on the open-loop/closed-loop! Coolant temp sensor was checked with multi-meter and was within spec. We also used a Snap-on Modis to verify temp showed on gauge and also shows everything else is operating properly. The dash gauge is off a little bit, but close.

It is very possible I might have gotten cleaner on the TPS! I have an extra one sitting around and will try that tomorrow. I don't have any bucking or jerking issues like I have experienced with a bad TPS before, but I presume a bad TPS might cause these issues?

Thanks again for all of your input! I know just enough to really get me in trouble and often cost myself more than just taking it to someone, but I still enjoy working on my own vehicles...especially when they are like Tinker Toys (TBI 350 is MUCH easier to work on than my Acura TL!!!!)!
