EBPV (Exhaust Back Pressure Valve) Suppose to close to help the engine warm up faster. Most guys just delete them when they go bad. It won't hurt anything to have the code. You would have to replace the sensor and probably the tube (clogged with carbon) to fix the problem.

Any smoke with the miss? The air intake code shouldn't be causing it but not sure about the other code.

no smoke wat so ever,and its a auto trannie,when im ideling you can tell that its a miss and when going 35 mph it feels like your in 5th gear,i have to hit the OD button to get down in 3rd till i get up to speed so it will plane out

A lot of times you have some smoke when there is a miss. Did you replace the harnesses under the valve covers and the valve cover gaskets? You might have to take it and have a cylinder contribution/buzz test to find out where the problem is.

[harley1rocker]

yes i have replaced the harnesses,and only the glow plug (prong) of the harness was messed up,look,there is a injector sittin in there a lil **** eyed,well you can tell cuz its not straight up and down like the rest of em

If it's not seated properly it could be causing an issue. Also, if the injector is a different code it won't run right. If you pull one you should pull all of them and replace the o-rings.
