This is the place to ask questions about your engine components like cams, valves, pistons? just anything that is generally "engine" specific.

For code 43, start by replacing your spark plugs and wires, shouldn't cost you more than like $30 total. Stock wires and copper spark plugs are fine. Neons don't really benefit from MSD wires or $50 diamond-plated-platinum 64 prong spark plugs.

Then reset pcm (just remove fuel pump fuse from under PDC under hood, it's easier than messing with battery cables and breaking the cheap terminal ends off), pull fuse out, go inside and get a beer or soda or whatever, then put fuse back in. See if light comes back.

The CEL (Check Engine Light) codes give important information. The CELs aren 't always 100% accurate, but they're pretty close. The CELs will help prevent you from throwing money at a problem that doesn' t exist. It's human nature to hope a simple inexpensive fix will get you back on the road. Your Neon doesn't care about what you hope, it's a machine with a problem. It's trying to tell you what's wrong. Do the key on-off routine and listen to your car. It costs you nothing. Post the code(s) and help will follow.

OK, first off if you are posting these kinds of questions there comes a point when you need to decide if this is something you want to tackle yourself or if this is something you need to take to your dealer/mechanic...If you feel qualified to to fix it then by all means do it..but sometimes a misfire can be difficult to source...My advice is to take it to someone qualified and then make your decision..

try the plugs/wires. if that doesn't do it, take it to a shop for a diagnosis at least.

common misfire causes that i see usually in order of frequency:
coil packs/wires
intake manifold leak
injector wiring
injector(s)
plugs
fuel filter

usually plugs will foul out due to the misfire, but cause is something else.
