I have a misfire on my 2009 Hyundai Accent on my 3rd cylinder. I plan to change the spark plugs and possibly the ignition coil, but my question is would I need to change all the ignition:confused coils or can I just change one?
Second question:
How long can I drive with it misfiring or is a have to fix it now.
Poverty sucks, I am a little strapped for cash and need to wait a couple days to fix it.

 

Are you sure it is the spark plugs and/or coils??
Have you tested it?
Or do you have so much money that you can chase a repair by replacing things blindly??

 

I have replaced all 4 coils and plugs twice. Engine light keeps coming on with code for #3 cylinder. Like you money is low. I Have driven car with engine light on for 3/4 days. Something is causing the coil to misfire. Will have mechanic try to figure it out. My guess is a clogged injector.

 

How are the spark plug wires?
If you swap wires does it follow the wire or stay on cylinder 3?
