[QUOTE="elrodalexander73, post: 1173449, member: 16217"] It sounds like you maybe sucking air at the fuel line gromets in the heads, those gromets over time break down, you aren't running a regulated return and these particular engines do not idle the best even with a tune and larger nozzles due to the dead headed fuel system, obs trucks will idle a little better without regulated return but the lift pump after hard accel will cause a slight surge in fuel pressue, I would verify that all injectors were ohming out correctly with the engine hot, not cold, and if you're dropping fuel pressue are you checking it at the head, and measuring both banks? I know a good regulated return is worth it's weight in gold on a 99 and up truck, even with stock injectors, I've seen stock trucks benefit in idle quality and throttle response. I don't think it's hpop related or it would idle worse as the oil temps increased. Have tried swapping an oil temp sensor, or checking to see if there is oil in the plug of the ICP sensor as well?
