I need to know what this is all about!!!!?

you need to go back with regular plugs in that truck ,for some reason the e3 spark plugs don't want to run good on the dodges at all,i tried a set of them before and they just caused a check engine light to come in my truck,i don't recommend anything but champions to go back in the dodges,you,ll get just as good of fuel mileage an performance with champions than you will any other plug made,good luck with it.

Put the old spark plugs back in and see if the problem goes away. Use a gap gauge to check the E3 plugs to verify the gap is right or wrong. A weak spark can cause the symptom you have. Wrong and ill-gapped plugs can do that too. A weak battery or bad alternatorcan leave you with insufficient spark.

That car does have on-board diagnostic, though not OBD2. Look in Chilton's or some other good auto repair manual to see how to extract the trouble codes if there are any. The possibilities are many and you might cut down the troubleshooting process this way.

did you have to struggle getting the plug wires off to change the plugs? brake torque the truck and try to get it to miss. if it misses, disconnect 1 plug wire at a time, and brake torque it again.when you get to the cylinder that does not make a huge difference, thats the problem hole. pull that plug, look for arching, check the gap and if possible, test the plug wire for resistance. 3,000 ohms per foot.or swap plug wires with the bad cylinder, and see if the miss moves to that cylinder. if not, swap plugs with another cylinder, and see if the miss changes cylinders

fuel filter?
