I am having with my 2013 Dodge 1500 truck with 11300 miles. I had it looked at by two shops and one had it for over a week. My engine light came on one day and so I took it in to be checked and it read “misfire of cylinder #3”. My ecm does not function and my gas mileage is in the toilet. They changed out the coil to that cylinder and the all the spark plugs did not fix it. They did a compression check good around 220. They re-flashed the main computer nothing. They replaced all my spark plugs and found that the last shop I took it for a tune up did not change all the plugs. But still nothing to fix the problem. They have performed many more checks and still cannot ID the problem. Bad performance 55mph and over. The shop stated that I should not take it on a long trip. Thanks paulolkowski@aol.com

 

What motor?
Do you still get the same code?
Check the plug to the dead cylinder,is it fuel soaked?
Ignition problem maybe,trigger?
Fuel issue,injector?

 

Strange, can you not take it to the dealer and have it looked at? A 2013 with 11,300 mi? Should be under warrantee.
