surgin down the fwy
 

howdy,72fj here my own 2000 5.9 24v started surging going on a 2.50hr drive last weekend it took about 1hr after driving cant seem to pinpoint the prob,reman v44 about
28,000 miles and tranfer pump im a stock freak so dont bag on me too much.fuel pressures staying to spec,(all new cummins sensors installed,new fuel filter great fuel milage.no loss of power,you can watch boost gauge go up down and here turbo going up/down and then stablizes no boost leaks pressure checked,no fault codes.new tps sensor no suction problems or return flow problems,i am starting to think the gov in v44 might the problem have any of you run across this problem befor,in my shop we only work on mid range and hd truck repair,other than that truck runs normal.any info would help:humm:

is your truck auto?

check the map sensor plug it gets a bunch of crap all over it i had this happen to me or it may be water in the fuel for a simple fix?

My auto surges sometimes. from what iv heard is it the tranny acting up and trying to figure out what gear it wants to be in.... i also would like to know what else causes surging haha.

lots of things can causes surging turbo, exhaust, fuel, tps, injectors, just check for codes and hope it don't cost a lot to fix lol what speed/rpm dose it surge

Don't know if it relates but my buddies 98.5 surges in 3rd gear at a certain rpm trying to decide if it wants to be in 4th or not. All he has to do is go twist the terminals on his batteries and it solves the problem.

sorry guys,forgot i put a post in the aftermarket section.i am thinking its in alt wire harness,kinda had same symtems w/my trans drove me nuts for about 2 months!vppower for your trans prob install a dtt noise filter can give you ph#if needed that will take care of that.any way going to rerout my alt wire away from alt and test drive and then who knows whats next,keep you all posted middle of week.:c:
