    Found a surprise in the intake manifold when I pulled it to check wiring searching for a P2138 code. Oil !!! Thoughts?

    First...my apologies. This will likely be lengthy. I have a persistent P2138 code after a mechanic did an mds delete (which I now regret) the mechanic couldn't fine the problem but I don't think he tried very hard. The code came up right after he did the delete. He said he test drove it but I'm...

    Strange starting behavior

    I have a 2019 ram 1500 hemi. Occasionally when I get in to start the vehicle and I press the start button with my foot on the brake nothing happens. I can press it repeatedly and nothing at all happens but within a few minutes it will just wake up and advance to the ACC position all by itself...

I would like to be able to do more advanced diagnostics and possibly even change some settings or at least have our mechanic do it. We have a small fleet of ram vehicles...

    Mysterious electrical issue, at least to me anyway.

    2019 ram 1500 with 149,000 miles. I recently had a mechanic delete the MDS system with new cam, lifters springs, etc. Even before this I was having some minor electrical issues like the overhead lights pulsing when the engine was at idle and an occasional check engine light that would pop up and...

    2019 1500 check engine light comes on based on the outside temperature and develops a misfire in cylinder 4.

    Thanks in advance for reading this and offering any input you have. I have a 2019 ram 1500 5.7 hemi with 135,000 miles on it. I usually keep my ram trucks until they fall apart which is typically 100s of thousands of miles. At about 105,000 miles in this truck started developing the hemi tick...
