If you still have the stock arrangement, there is a sheet metal deflector riveted to the bottom of the throttle plate. Ive' seen the rivets loose so many times, there was actually a vehicle that the deflector came off and lodged into the opening so the engine took off.

I removed mine several years ago and plugged the holes.

Let us know, I have another suggestion if that's not it.

Thanks for the suggestion! No, I just checked and everything is good and tight in there. No loose rivets. The throttle is also not sticking.

Thanks for that! According to my multimeter, as 72 degrees, it's testing at 2890 ohms. Post warm-up, at 190 degrees, it reads 214 ohms.
