tks again for your help. sorry about the teenager remark. it was only meant to brag you up. listen my son doesn't have the experience as you and he lives on an island off the coast of maine...so getting to the dealership and giving up your only means of transport is a big deal (and expensive) and the problem still doesn't happen all the time making the whole trip a gamble (to say nothing of the cost of a rental to use in his business while the dealership waits for the problem to happen.

for $100 he can have a TPS shipped to him and if it is simply taking the two bolts off to remove the TPS and replacing it with a new one, i think he can do it. using an ohmmeter to check resistance between terminals is something else. does it make sense for him to replace the TPS himself and if that makes no difference, arrange to get the truck to the dealership? what are the things that might go wrong with the replacement of the TPS? tks again for your time. r u on the lower cape?
