Angry Need some help with my 2000 Mustang

Hi
I have owned my 2000 v6 mustang for almost 11 years. I drive it every day for work and have put 362144 miles on it so far. I just went to get my sticker and was told my check engine light is out and my car shows a P0304 OBDll code for a cylinday 4 misfire..
What I need to know is 1. how do i change the bulb in the dash cluster and 2. How do I correct the misfire in cylinder $. My car seems to run fine and I have not had any real problems with it
Any advise would be very helpfull

Dad707, how old are the sparkplugs? They might be getting to old to perform right
How about plug wires, are any of them (especially #4) burnt, they might need replacing, u can get a set of msd wires for about 75 and it will get u about another .5 mpg
Some simple things to check first before you get to in depth

BV heads, P&P lower, windstar upper, comp 218/226, 4.2 bottom end, 3k stall, flow 40's, O/R x-pipe, Pacesetter lt's, Xcal2, 65mm tb, CAI, 8.8 w/ 3.73's, MM LCA's
coming soon: blower cam and intercooled M112

i would have left that part out..

but definitely look at the simple stuff first.. inspect the plugs, see if theres any fouling/buildup on them.. make sure the wires arent cracked, melted, or touching anything they shouldn't be(as that can cause arcing and failure to ignite the cylinder.

right thats why id have left it out.. could have just been that your wires were old and not working as well as they should doesnt matter anyway

to dad707 did you get the car worked on recently or within last 3 to 6 months, reason why i am asking is because it might be something that was looked over, alot of times if your check engine light isnt on then you would have no reason to clear it, and if the light is blown then you dont know it is on. i would try going to A.Z. and having them clear the code if you dont have a reader. then see if the light comes on after you replace it. also the light is pretty easy pull off the headlight knob, there are 2 screws on the top of the speedo bezel undo those, pop the bezel out, then there is 4 bolts around the speedo undo those, after that try to get your hand behind the speedo and there is 3 harness clips, undo those and its out, now you have to pinpoint which light is the CE, also before hand if you want to check which other ones are out follow these directions
