Can anyone tell me why that after doing my deletes and driving the truck for 3 weeks it all of the sudden decides to throw code P0488 (EGR Throttle Control Circuit Performance)? I have cleared it twice now and it just keeps popping the engine light back on. Thanks for any help.

 

did you unplug the throttle valve on the side of the intake horn if you didnt it would bring up that code.

 

Yeah, I forgot to unplug the one underneat the intake horn. Oops.

 

yeah that'll do it let us know if anything changes
