well, its been doing this for some time now. i can let it sit overnight and in the morning it will crank up and run just find. but at the same time it doesnt always fire right up. i have put in countless cam sensors, an icp sensor, and fixed a break in the wire harness right under the turbo. at idle speed the motor will shut off like its either not getting enough oil pressure or fuel pressure but sometimes it will idle just fine. its a 96 f-250 with only 140,000 on it and im wanting to get this thing running right before i do any mods. its been throwing the cps intermittant code, boost pressure higher than desired, and injection control pressure higher or lower than desired codes but while driving it i have no problems until i get to a red light.
