P0455 is Evaporative Emission Control System Leak Detected. Check and/or replace the gas cap first: http://www.obd-codes.com/p0455.

#6 of 7 Cylinder 5 misfire on 2002 ram, 4.7 liter engine

I have a code reader. I don't have the specific code number in front of me at this time. I have changed the spark plugs, all eight. The truck has 130k miles. This code prompted me to change spark plugs. Code reappeared. I bought a new spark plug coil for this cylinder. Code reappeared. I switched coil and plug with cylinder three. Code still reappeared and the number five cylinder misfire. I have cleared the code, prior to any of these adjustments. I have noticed, that after a cold start (not cold outside, just engine), and I press on the accelerator pedal to move, the engine service light comes on. I checked the code and it is the same. I have had the code checked at two other different locations ( AutoZone and Walmart). The same code appears on those code readers. What could be the problem, other than what I have tried?

It would be very helpful to have the specific code. To get it, cycle the ignition "on- off- on -off -on" under 5 seconds, without starting the truck. The code will appear where the odometer displays.
