help needed again...
well after a week of nothing but problems with the truck i got everything running right today, water pump replaced, two new batteries this week, new ICP, oil change, ect. ect ect... now as i was driving down the road today at about 45-50 i noticed what sounded like an exhaust leak, stoped the truck and found the fairly loud whomp, whomp whomp, sound comming from the air intake... I hate to say this but i think i have a burnt or bent valve..... any other ideas? i will try to post an audio clip tomorrow

Could have a bent pushrod or broken rocker. either one of those on an exhaust valve will cause backfeed into the intake.
if you have an infrared thermometer you can check each exhaust port at the manifolds. the cold one is the one that's not working

Look for a problem on one of the exhaust valves.
