[QUOTE="Mickey427, post: 1423281, member: 18050"] Yesterday I swapped out the cam sensor with no change. Checked everything over a hundred times. Also put the old filter back on with no change. The bypass valve was still in the filter mount. Took it to my cousins shop and put the computer on it and it miraculously started working just fine. Or at least hardly showed itself. It acted up a little bit with pressure fluctuating, could see it on the icp pressure graph momentarily here and there but ipr duty cycle stayed flat. Icp pressure at wot 3k rpms was 2500 at 32-33 percent duty cycle. Idle ipr duty cycle was low so there isn't a leak somewhere. Only thing I can think of is replacing the ipr and see what happens. On the way home after unplugging everything it started acting up again so could it possibly be IDM related? How flat and steady are the icp pressure on the graph supposed to be? Mine was pretty choppy even when it ran smooth. Sent from my SM-N900V using Tapatalk [/QUOTE]
