Glad you figured out that TPS is for Throttle Position Sensor. I've seen a lot of the TPS issue mainly in vehicles that drive pretty much consistent speed in city driving. I first experienced it myself (seems like eons ago) in our old 1983 Mid Sized LTD.

 

do you think when I purchase a new sensor the issue is solved? And can O do it by myself

 

A new TPS may or may not resolve your problem. You can use a Digital Volt Meter and Ohm out the pins to see if you can detect a short (0 Ohms) in the TPS. Or just go ahead and throw a new TPS on. The TPS is mounted with only 2 screws and 1 electrical connector.

 

thx there is one thing I want to mention and yesterday I was driving on the highway bucking again I did put my car on cruise control and he was driven smooth without bucking

 

I want to thank the people who gave me advise I did change the sparkplugs and my problem is gone it drives smooth again great thx Kulmbube

 

Good morning I have a ford taurus sel 2009 , my wheelbearing rear R is making a terrible noise so I have to replace that piece my question is: can I go and change only the bearing (by a specialist) or do I need to purchace the complete hub thx

 

It looks like the rear hubs are a complete assembly. There are two different hubs depending on the application.
