ok. i can't find the TPS on the 5.7 Hemi. Can somebody take pics or tell me where to look? I appreciate it.

 

The Hemi's dont have TPS...

 

Well do you thinks it the EGR valve. Cuz my check engine light is on and its doing that surging crap.

 

Are you pulling any codes? You can go to autozone and they do it for free. Have you checked your throttle body? A DirtyTB can cause surging. For some reason on the Hemi's you have to clean the TB like every year. I think its from that damn oil breather that makes them so dirty. My truck was riding rough, turns out my throttle body was nasty so I cleaned it. Been fine ever since.

There also a DIY on how to clean it...
