Engine surges while braking
I noticed this weekend a wierd surging that has never been present before. When the truck gets up to speed, I push in the clutch and apply the brakes is the only time it happens. It does not do it (that I can tell) if I only push the clutch in. It's not warped rotors catching the brake pads, because it continues to surge briefly after comming to a full stop. I recently have had the throttle body off for a cleaning. Replaced the gasket, with no vac. leaks. Could it be somthing on the TB sticking? I did a search through the boards but found nothing that matches my problem.

Yeah I have one of those code readers you get from Autozone, but haven't had the time to use it yet. With the Holidays and dad in the hospital it's hard to find time. But I never gave the TPS a second thought as to be the culprit. Thanks.

Fixed It !!!
It turns out that it was the throttle idle adjuster screw. It was turned in too far and the engine was idling at a very high RPM. (don't have a tach.) So the throttle sensor could not compensate enough when I let off the gas. I backed out the screw enough to lower the idle speed but not stall it out. Problem went away. Thanks for the suggestions and help guys.
