Asked by Cliff Mar 14, 2019 at 12:53 PM about the 2010 Dodge RAM 1500 SLT Crew Cab 4WD

Question type: Maintenance & Repair

In my 2010 Dodge ram 1500, I keep getting a
p0303 cylinder 3 misfire code. to date I have
replaced all 16 plugs the coil pack on cylinder 3
tested all my connections for both coil packs and
the injectors and troubleshot my injectors to see if
I had a faulty injector, which I did not. My question
is what is my next route to take do I begin to
troubleshoot the PCM because I'm currently at a
loss.

Camshaft position sensor has been replaced. What's the best way to check for intake leaks? Can I use the old school method of soapy water in a spray bottle or is there a better way to check?
