Default Code p0302

Says #2 cylinder misfire? Anyone know how much coil pack is? Says could be plug, lead or pack. Had plugs done couple years ago. Just happened and havent looked into it yet just parked and went to work.

Before buying coils move the coil pack to a different spot and see if the error follows (reset the code when you move it.) This will tell you if it's the coil or the plug/connector. If it stays then replace the plug. How many miles do you have on these plugs?

Also need to know at least the year and the engine as well before more troubleshooting can occur.

they were replaced last Feb so less than 20kms. I'll do that first. I'm going to pick one up for standby just in case it is. I haven't looked in there yet but are they banks per side or individual for each plug?

If you are 8 cylinder:
Pass Driver
4_____8
3_____7
2_____6
1_____5
Assuming it's 98 or newer. Not sure on the sixes but think it's the same. One coil pack per plug.

Hello
just so you know, unless they have multiple plug wires coming out of it they are not coil packs! I think this misnomer may have started because parts people do not understand they are COP's (Coil On Plug). if it sits on top of the plug it is a COP NOT a coil pack. This could be important to know if you need to speak to a Professional or want to get the right part say on the Internet.
