ok well this is an on going problem i have had, when the truck runs for a while and im sitting in traffic or at a long light it will start to idel like ****, until i start driving than it smooths out. along with that problem its been struggling to start, it will turn over a longer than normal eventually it will start. the plugs and wires have recently been changed, and maybe a year ago the whole fuel system was replaced, tank, pump lines injector. At this point im thinking it has to be fuel
any suggestions ?
thanks
Eric

someone said the EGR might be hung up and to remove it and spray it down ..

 

anyone have any pics or diagrams where the EGR is located .. ? hopefully ill get it done tonight

 

Front of the motor, below the throttle body (where the intake hose attaches). Looks kinda like a soda can.

You'll need at least 9" of extensions and a 10 mm socket (and stick a little piece of paper towel in it so the bolt sticks better) - for the driver's side bolt. For the passenger-side bolt, you'll need a 10 mm wrench; a ratcheting wrench makes it easier.

You'll also need a replacement gasket. Get the one from the HELP! section - it's screened.
