Truck started shaking then turned off.
Engine rumbles violently.

No Oil leaks or any other kind of leak.
New Plugs and Coilpacks.

Scanner showed codes for
P0304: Cylinder Misfire
P1414: Cylinder 4 Reactivation Control Performance

What could possibly be the cause? Before I send her to the mechanic.

 

Well first, the PCM thinks you have the wrong oil type in there. Think I would address that first.

Next, cylinder 4 misfire. Likely related to the wrong oil.

Make sure your gas cap is tight......

 

The engine is correct, I put almost 7 qrts of 5w-20 Mobil One.
Those are old codes, has a new gas cap.

 

Clear the codes then, drive it for a bit, and see what comes back up.

 

Nothing changed unfortunately, the truck still shakes hard and then dies.

 

Any new codes??

 

The same codes appeared, but the “wrong oil code” doesn’t.

 

All of them???

You may have an MDS solenoid hung up......

 

Yes, the same codes for Misfire and Cylinder 4 reactivation.

MDS huh? I hope they’re easy to pull out!

 

No info on how hard they are to get to...... I haven't had the opportunity (misfortune?) to play with one.
