you can buy a tps on ebay cheap... or about anywhere online

 

Never mind guys. Just blew the head gasket......

 

Sounds like time for a motor swap or salvage yard swap and if you go around to the junk yards and look you may be able to find one laying around I wouldnt get a tps by itself unless you know how to calibrate it yourself, I cant help on that part of it, sorry about the luck but it sounds like you found the reason for the misfire
