Have problem with dt466e in a 2001 4300 international box truck 170000miles. cranks great hot or cold but after it gets 150 or 160 degrees the exhaust is getting real eye teering strong but no smoke setting there idling. Before it gets up to temp it doesnt smoke except for normal amount of dark fuel smoke you get when you rev it up and no flutter,,..Buuut when it gets warmed up setting in shop you get a high rpm fluter and unburnt fuel smoke just when and only when it flutters, this is when you rev it up to 1700 -2000 rpm then stab it, you can let it go back down to 2000 rpm and then stab it and it will keep doing this. Some sometimes it will do it from a idle to wide open if you just stab it. it never does it from idle or higher rpms if you ease into the throttle only when you stab it. Out on the road you nottice it when going thru the gears, flutter, smoke, low power, then it clears up and power is normal. hooked up to pc and did koeo and koer checks and every thing shows good no old or new codes pulled injectors and had checked they were above and below fuel settings 3 and 3 replaced all injectors and and problem is a little better but still very much there replaced cam sensor and this didnt help at all. Any help would be greatly appreciated thanks in advance.
