Ok recently my truck developed a misfire under hard acceleration. Went to pass a truck on the highway, put the hammer down and not what I was expecting. Bucking, hesitating etc...

Took it to the dealer next day(under ext. warranty) They checked it out, confirmed the misfire and got the bad news today.

Dealer tells me the Throttle Body needs replaced. Dealer also tells me that the throttle position sensor is built right into the throttle body and is not replaceable. Hence why a whole new TB assembly.

Here's the catch, It's not covered under warranty and supposedly $650 and change later, this will fix the misfire.

Is the TPS actually built right into the TB on these trucks? Given the cost, I plan on doing this myself if possible. Any insight, info or whatever you guys got, I'd appreciate! Thanks in advance

 

I think so since you probably have electronic instead of cable to the throttle. If its not covered, a junkyard should have lots of those for pretty cheap.
