What is your question?
I changed all the vacuum lines, changed the ERG, and solenoid pump. The truck stumbles once i put the vacuum line on the ERG valve(runs smooth with out the vacum line on the EGR vavle). Can anyone suggest a system to look at?
sorry its a 3.0 V6 2WD
Now, try switching vacuum hoses at EGR control solenoid. The black thing with two hoses and wires going to it. Like next answer suggest wrong hoes to EGR.
