I have 03 excursion witch have no power/boost.Starts fine,idle is good no smoke etc.I have scanned it with snap-on and i get p2263 in koer test.I checked turbo,vanes,actuator turbo oil feed (over 60psi @idle)there are no leaks or gloggs in intake or exhaust.I have cleaned egr change map and ep sensors.All data seems right.After few miles with hard drive almost constant wot over 3000rpm and i see small charge rise.About 24psi max and about 14psi ep pressure.Oil ,oil filter ,fuel filters and air filter been changed.Fuel pressure measured ,55psi.Disconnecting maf makes no difference.icp keeps under 30% at idle.I have no ideas enymore.Please help!And sorry about the terrible language,im from finland and my english arent very good.:dunno:

Yes,the turbo vanes.I been disassembling the turbo, get all rust out and check with compressed air that the vanes are moving proberly.I´l even try to get some boost by getting straight 12v to turbo vane actuator and give hard gas to it but no boost still shown.When i go and drive it warm and get deep accelerate it accelerates even pretty good at over 3000rpm and specially if i had over 60mph but in the normal town driving its good dam powerless.What makes this so hard is that theres isn´t official importer with american ford wehicles and you cant even get proper safety recalls fixed.I been putting 2 bottles of redline diesel additive in tank and drive but that have been makes no difference.I know it´s have been driven poorly fuel and the filters look real bad when i changed them.Could it be just glogged injectors?

You have a screwed up sensor somewhere that is confusing the PCM and making it very laggy. Mine does the same thing sometimes... pisses me off.

Sounds like it's time for some data logs.

What sensor couldt affect so much?Like i was telling earlyel i´we been scanning it with snap-on scanner and all data seems normal.I´l think i´m gonna get the tank out tomorrow and see if the pick,up is glogged.I´m not yet been measured the fuel press while droven but that is also next to the list.I´ve try to solve this problem with performance diagnostic chart but no results yet.The map sensor shows [email protected] and ep 0psi shouldt they show same readin at koeo?I been repairing another 6,0 excursion last year and it shows same readings and worked fine after i get the intake manifold leak fixed.Both cars are 03models.Also both have labels telling that they have updated ecm or something.
