Electric Issue?

[landonl52]

Hello newer to the forum and never seen an issue like this before but I’m on vacation and stuck on location until I can figure it out.

I have a 2012 RAM 3500 high output.

I just deleted it and had it tuned by DRD last month but I drove about 650 miles no problem other than it threw an engine light for intake air position sensor out of range.

Replaced sensor when I got here and that went away but got in it to sightsee and it has an intermittent crank no start condition.

The Programmer shows P0607 and staying at my brothers house he has a scanner so we got it to fire finally and it’s only running on cylinders 4,5, and 6.

Checked all the simple things then let it sit went out an hour later and it fired up like nothing was wrong.

2 key cycles later engine light shut off and it was fine so we went out driving and it would intermittently loose the front 3 cylinders and they’d come back randomly always together.

Now she’s dead again and don’t know where to go with it.

Frame ground by the left front tire was cleaned as was all terminals.

I don’t think the programmer would have any effect on this kind of issue.

Any help would be awesome just wanna get home at this point

Let's see if @DRD can shed any light on this friend.

My guess is a faulty PCM.

Tuning nor the tuner would cause this issue.

Is there any grounds that might cause it too or not really with that?

Bad batteries etc...?

Anything is possible but typically a bad ground causes the engine to shut down completely.

Dropping cylinder banks sounds more like a faulty PCM.
