2002 powerstroke 7.3 chip,exhaust and intake upgrades. My truck will miss at higher RPM's and die at lower.It will do it with or without the chip.The kicker is it will only do it when its raining or heavy fog.The code that comes up is cam sencer,I changed the sencer and the miss is still there.I used a water hose with a sprayer and sprayed everything under the hood and under the truck and I can't get it to miss with the hose.
