ok can someone help me out i just put in a pmd relocator kit and now when i take it up to 2000 rpms and let it idle back down it stay up for a sec and spits and sputters all the way back to idel and some times stalls out im of ideas some one please help me out

Oddly enough it sounds like a PMD/IP issue. Was it a new pmd or did you just relocate an older one? Kms on truck? IP ever replaced?

Did it happened before? There is a batch of Dtech or Flight System PMD that caused surging.

no its a new pmd relocator kit from pensacola diesel i never changed the ip whats a kms? and it never did this before i put the new pmd on it the old pmd just went out on it? do you think it might be the injector pump? i would really hate to buy one of them they are costly

i think the chip in the new pmd was a number 12 also would that have something to do with it?

Pretty sure the chip only goes to 9, and KMS is kilometers so since you didnt know that you are probably from the states so how many miles are on the truck?

i have 172,000 miles on it i just looked up the pmd that i bought and its a flight system pmd with the #9 resitor

i called up pensacola diesel and they said it sounds like the amrature in the ip does any one have a break down on the ip so i can try and rebuild it my self
