MuddFoot Posted October 23, 2014 Author Share Posted October 23, 2014 egr. i messed with everything but it pulled the vac hose off and boom runs perfect. but look at all the spare parts i have laying around now. Link to comment Share on other sites More sharing options...
cruiser54 Posted October 23, 2014 Share Posted October 23, 2014 So, the EGR solenoid is/was not closing completely, or the ECU was not giving it the correct signal. Link to comment Share on other sites More sharing options...
MuddFoot Posted October 23, 2014 Author Share Posted October 23, 2014 i changed it with one i had here and it was still messing up. so i left it pluged in and unhooked the main vac line and plug the line if you unplug the solenoid it runs even worse i guess it has to be plugged in no matter what. so the electrical has to stay plugged in and the vac disconnected and it runs perfect. so I'm going to start cleaning up the truck and getting ready to paint.
