truck shuts off/hesitation
Little bit about truck 2000 f 250 @310,000 miles. Six speed trans.
I can give more info if needed, but get to the point. the truck Will cut off sometimes when driving or have a hesitation. ( as if you let off the gas and back on. I have battled with this for about 6 years on and off. within the last couple months it is horrible. I can't drive anywhere without a problem. When the truck cuts off sometimes you let off the gas then back on and it would continue running again, but in the last few weeks I Will haveto turn theswitchoffthen back on to get it to continue running.
I have AE scan tool but not 100% sure what to check for as far as. what sensor. specsare
so from reading other posts. ICP Voltage .24 KOEO .83 Cranking @480 psi when idling
I have been getting the code for the CPS when it shuts off. but now my codes are 1670Electronic feedback signal not detected (This has just come up with in the last week) 0381Glow plug heater indicator (This has just come up with in the last week) 0232Fuel pump secondary circuit hi
cct test #3 and 8 fail (this has just come up in the last couple weeks).
buzz test is good, gp test is good
hpop, ICP, IPR, GP Relay has never been changed
Around 2 years ago all o-rings that are fuel/oil related werereplacedinjectorcups, water pump all coolant and hoses were replaced with new ones. bp sensor and tube, IPR rebuilt
New uppipes , FRX (middle spring used), HPX and 6637 DIY filter installed about 6 months ago. Any ideas where to start looking/diagnose?
