take it to another dealer, there could be a leak somewhere in the fuel supply lines going to the cp3 and its drawing in air, is the bleed screw on the fuel filter tight? as tight as can get it with you fingers should be good enough

you can use the hand pump on top of the fuel filter housing to pump post of the air out it takes about a million pumps but fuel should star comming out thhe bleed screw once its ready, the cp3 works under a vacuum so it draws it own fuel, if theirs a small hole in the fuel lines somewhere itl suck in air and cause the engine to run like crap.
but there could be something else wrong with it. but that's where i would check first if i didn't have a warranty
