I have a '03 with 140K miles. I have regularly maintained this truck and ran a fs2500 oil filter. No chips. Bone stock. But it will not idle right whenever you stop. It drops 2-300 rpm then surges up then settles back down. I have had 19 fuel injectors in this truck. Hpop. ficm. icp. egr. headgaskets. etc. This truck has a dealer file that want quit. I have had to deal with the downtime, but the cost has been reasonable. I highly recommend the Ford extended warranty. I like the truck but am tired of putting up with the down time. In case your wondering that is an injector every 7200 miles on avg.

I am not 100% but I believe there was an FICM flash TSB for this issue. Did you post it over in the Problems forum. There are a boatload of master techs that will most likely chime in.
sounds like an icp my buddy just had his go out and it was acting the same way.
