Michael,
Those throttle bodies get gummied up a bit too. I clean them with a rag and a little solvent and it makes a huge difference. Be sure to shoot some solvent through the idle bypass hole.

I haven't touched it in quite some time, seems some good gas did the trick, she fires up like she always did ... no hesitation. I just made the trip out here to CA 1280 miles or so hauling the Camaro on a U-haul and she never missed a beat.
