My truck has a wicked bad bog at idle speed, and it lopes when idling cold. I have determined that something in the EGR system is the problem. when I unplug the vacuum line to the EGR valve the truck runs awesome, leading me to believe that the solenoid is allowing the valve to see vacuum at idle speed when it shouldn't. I put a new solenoid in and the problem is still there, If I unplug the ECM wire to the solenoid the problems goes away, I have pulled the valve. it moves freely and I can here the pintle tap closed if I open it and close it. Has anyone dealt with similar EGR problems? short of buying a new valve which are rather expensive up here in Canuck land Im lost as to what to do next.
