TRUCK HAS A BAD MISS AND HARD TO START WHEN COLD

[cory58]

hey guys i am relatively new to the site, since i have joined my trucks been having the problems. i get a real bad viberation when just slow throttle from 35 to 55 then it smoothes out if i gun it there isnt any shaking. the only way i can think of how it acts is missing but u can feel it shaking. the hard starts i imagine are the glow plugs or the relay. i get a lil white smoke when started up and thats it. i think my miss is an injector or two not working right but i dont know if there is anything else the truck has 173000+ on it

it has done this since i bought it but for 3000 dollars from an old farmer i couldnt pass it up

Do you feel its from the engine or drivetrain issues?

Is it a 5spd? May be the dual mass flywheel coming apart.

I'm gonna bet on a UVCH (Under Valve Cover Harness) coming loose...

its an auto recently rebuild upgraded shift kit and torque converter, new u joints on all drive shafts. i dont think that is is a drive train issue because there is no shackin when u let of throtle, and because everything was just done 5000 miles ago when i first bought the truck. i know i should get a buzz test and a cylinder contribution test done but i dont have the money right now i just didnt know if there was another way or maybe a quick fix i changed the oil and filter and air filter and fuel filter on top the engine last week. didnt help nothing

that could be to check that all i have to do is pull off the valve covers and make sure all connections are tight? this is my first diesel i have worked of gas my other truck is an f150 with the striaght 6 thats what i use to drive now i just havent been able to get this truck fixed up, but for the price i couldnt pass it down

Yeah Tom is probobly right. Here check this out Under Valve Cover Harness

would that still be the case if my check engine light has never came on? i want to buy that auto enginuity for my laptop but its winter time and mother nature isnt helping the construction workers here in ohio out. i have all the time in the world to mess around with fixing my truck but no money to buy anything

Its possible. Really if you can find someone to scan your truck its a great starting point without wasting your time and money throwing parts you might not need at it
