Check Engine Light and Misfire Help Needed!

I’m facing a frustrating issue with my car where the check engine light keeps coming on, and I can feel a misfire while driving. I wanted to reach out to see if anyone else has experienced this and could offer some advice.

What I’ve Noticed:

  • The check engine light comes on intermittently.
  • The car feels like it’s hesitating, especially during acceleration.
  • Sometimes, I can hear a sputtering sound from the engine (not sure if that’s normal).

Possible Causes I Found:

  • Spark Plugs: I’ve read that worn or faulty spark plugs could lead to misfires. Should I check these first?
  • Ignition Coils: I’ve also seen problems with ignition coils can cause similar symptoms. Does anyone know how to diagnose this?
  • Fuel Delivery: Could this potentially be a fuel pump or fuel injector issue? What signs should I look for?

Next Steps:

I’m debating whether it’s best to troubleshoot this myself or take it to a mechanic. For those who have dealt with this, how did you determine whether to DIY or get professional help? Any insights on fixing a misfire or tips on what tools I might need would be greatly appreciated!

Thanks in advance for your help!
