Errr no you probably crossed wires and plugs on the distributor cap when you replaced them, that is why you are supposed to replace spark plugs and wires ONE at a time so you don't cross them up. Yes, even replacing the cap itself you need to do the wires ONE at a time, using the old for reference as you wire up the new one, because failure to do so will cause... A misfire!!! So here comes the fun part, you get to visually inspect each and every wire coming from your engine and going to the cap to make sure it's plugged in correctly. The process is a bit time consuming but not as daunting as it might seem. Firing Order on Dodge is Clockwise 1-8-4-3-6-5-7-2 And your cylinders from front to back Pass: (front) 2-4-6-8 (back) Drivr: (front) 1-3-5-7 (back) So for example, find your number 1 wire and follow it back to the distributor cap. Now, the NEXT wire in clockwise order SHOULD be the number 8, follow it back to the engine and hope it does actually go to the number 8 cylinder... Don't go pulling off too many wires, once again remember to do this ONE wire at a time. And technically that's all you should need to troubleshoot this dilemma.
