2016 Ram 1500 Eco Diesel, Blue, Big Horn, Ram Boxes, 4x4, 3.55 gear ratio,
Hey guys, I am looking for your input. Tell me if this is normal or not or if you have an idea what is going on. Any time my truck starts when the coolant temp reads below about 70-65 degrees or lower, and once it revs up into high idle (Yes i have the new GDE Tune) or if i was to take off and drive getting RPMS above low idle the truck will start shaking. The colder it is the worse it is. it will only do it until coolant raises above 70, but wont stop doing it either until it reaches 70 or i press the brack the the tune lowers my rpms but as soon as i revs up again it is back until i reach temp. Now I bought this truck in oct 2019 I believe. It had a brand new engine when I got it. At the time it was warm enough it never did it. Truck went in for service in November i believe and the flashed to AEM without me really knowing all about that issue. After that ofcourse the truck always ran like crap until it warmed up. Me and the dealer blamed it all on that, which i am sure most of my problems at the time where that at the time. Once the weather warmed again it went away. Still unhappy with the AEM update, I eventually purchased the GDE Tune. I was nervous about spending that kinda money, came from a world where tunes were frowned upon. Once installed, I admit I ate crow and the truck was like a new truck again. Gotta hand it to them, they did good. Coming from me that is saying something. After that I did notice once the cold weather returned the shaking came back. Called GDE, they suggested perhaps a glow plug was acting up. I had wondered that too, but have no warning lights or codes for that, shouldn't i if that where the case? Eventually i took it to the dealer again for that and some other issues mentioned the glow plug. Dealer was convinced this was a sign of the plugged up intake manifolds as bulletins have talked about, they screwed around with it forever and I finally got it back in april I believe. Ofcourse by then temps had warmed up and it wasnt doing it anymore. well now it is november in IL and the Temps have dropped. Guess what, it's back. i almost feel like it is getting worse. once the truck warms up over 70 it smooths out runs smoother and you would never know it. I realize diesels need to warm up, but in have been around alot of deisel engines and never seen one shake everything this vigorously. Does everyone elses Eco do this? I have never seen any other coments about this and the other day a coworker had to give me crap about it sounding like crap warming up. and all these guys have diesel trucks too, other brands ofcourse. Any idea guys? Sorry i am long winded. Hope I posted this in the right section. I have a mechanical back ground but I am no mechanic. I am open to ideas. Thanks in Advance.
