Hey there has anyone had this part rebuilt? I am thinking that mine has failed and before I drop 700 for a new one I am curious if anyone has had this problem before?
Symptoms are rough low idle and next to no throttle response. Throttle body itself has been removed cleaned and inspected. No vacuum leaks present either.

Thanks in advance

 

Was the TPS installed correctly. It’s spring loaded and needs to be installed so it can control the throttle body

 

Not refurbished, but I've seen a lot of them sold used on eBay. Like this one, and many others.
