I done a cylinder balance test with a snap on scanner and it all came back good all cylinders were 100% equal even when i would drive it and get it to miss. on my way home again today i got P0107(map sensor) i forgot all about the map sensor on the back side of the pusher intake. So i gave a little tug on the plug and it slid off the sensor!! I put it all the way back on and went for a drive. I got it out on the high way going up a big hill in 5th and let her have it. Of course started missing but not as bad i don't think. It didn't jerk as bad when it missed and i have to really lay into it. No more missing at idle tho. i did notice rail psi was around 22k going up the hill. i don't think that's low enough to make it pop like the rail is going dry do you? Also after i got into it hard another time it through the p1507. crank case restriction. I have about a four foot hose coming off the valve cover venting into the atmosphere. crank case filter has less than 15k miles on it. any more ideas where to look? I wanna look over everything before i take the injectors out and get them tested. Thanks for the help!!
