Throttle cutting back

Thanks for the response.. I had ruled out a fuel problem. I changed the filter and it seems to have plenty of power and fuel delivery until the point where it cuts off and rpms drop.
the .76 number is what it should read at engine off/ key on but the reading I have at that is .70 leading to the idea that the tps has atleast some issue indicated.

did you check it with the key on and throttle all the way forward. you can knock out the metal mounting pins on the tps and rotate it counter clockwise for more voltage. if that does not work you can drill those holes out to rotate the tps even more for increase in voltage. i did all this but mine was shot. a bad tps will constantly be hunting for gears and lock and unlock the converter. i would try this before spending the money on that spendy piece of plastic as your issues don't seem to be tps related from the sounds of it. i really think it is your gov. springs!

I talked to Mark at tstproducts.com who said he had never heard of governor springs wearing out. He suggested I look at the overflow valve which is a common cause of low power and/or other fuel problems.
I took the OFV out and it looked fine, but before reassembly I stretched the spring as he recommended and the truck now runs like new - even idles much better. I will be replacing the unit with a new one. I wanted give an update for anybody having a similar problem in the future. thx to all
