Ok, lets start by saying fuel pressure is within range, changed spark plugs, air filter and no engine codes! Vehicle hesitates while accelerating and sometimes at steady speeds. There is no egr valve for this year of truck either. 2003 dodge durango 4.7 102k. What else could be wrong

 

Repost in the first generation Duraqngo section as this is the general forum. Did you clean the throttle body with the tune-up?
