Hello,

I have a 2013 Ram 1500 Laramie 5.7L. Truck was running great. It has about 144K miles. Last Sunday the check engine light came on. I had the code checked and it was a misfire on cylinder 5. I could feel it misfiring, but wanted to confirm what the computer was seeing. I replaced the spark plugs and the coil for cylinder 5.

Any ideas about what to check next?

Does anyone know how to check the connections to the coil to see if they are getting proper voltage?
