Hi everyone,
Lately, my 2010 Jetta has been idling a little rough, and the acceleration feels odd. I'm starting to wonder if it could be related to the spark plugs. For those who've experienced this, what are the typical symptoms of bad spark plugs you've noticed?
The check engine light hasn't come on yet, but I'd rather catch it early than wait for something to go wrong. Any advice would be great!
