Hey guys just looking to get some feedback from you experienced 6.0 owners and hopefully some ford diesel techs. Just switched to rotella 5w-40 synthetic in my 06' from 15w-40 and the night I did it the truck loved it, smoothed out idle and seemed to run a little quieter. Next day 20 minutes down the road its starts jerking/bucking when I was at the stoplight and everytime I would get into the skinny pedal it would buck and jerk even more. After ALOT of research about the problem last night I finally found some numbers to compare on my CTS to see if I could figure out the problem, so I go check them this morning. Turns out all the readings from my CTS are what they are suppose to be .
FICM: 48 volts when starting
ICP Voltage: .2 KEY ON , 1 When cranking
ICP Psi: over 500psi when cranking
Also to look up if it is a possible turbo problem a tech stated to check the barometric pressure and MAP reading
MAP reading: 14 key on
Baro reading: 14.6 key on
Today I did go out and unplug the ICP plug and the truck seemed to drive better but it idled worse. When its plugged in, truck idles rough and drives worse than when unplugged so Im figuring ICP. Any input would be appreciated guys, I was going to order the ICP so I could hopefully have it by the weekend, hate not having a vehicle at 100%
Truck has 196,550 miles and it started doing this at 196,500..happened while running innovatives x street other than straight pipe truck is stock. Returned it to stock tune today and it doesnt make any difference.
