Stalls when I stop. 2002 4.0 edge engine stalls then stalls again if I put in drive doesn't stall in neutral or reverse. Will start back up and eventually run again. I cleaned the Idle air control and it worked for awhile. I replaced the idle air control and it worked for awhile then I replaced the EGR valve and it worked for awhile. But the problem kept coming back. I just replaced the EGR control solenoid. It is working but it now has a hard shift from 1st to second gear Its not bad but different. Did I get a bad solenoid or do I need to keep going down the line to the DPFE.
