Hello

I was cleaning my engine and sprayed water on it and now it's mis-firing and I have a check engine light. This is a 2004 QUAD cAB RAM 1500 4.7 engine

How many miles are on the truck? Are the ignition parts original? I'd start with a tune-up; you may also need a coil but save yourself the money for now and just do plugs & wires.
