Should I just replace all the spark plugs and coils?

That is an expensive guess. We identify the misfiring cylinder and the reason, then replace only what is actually at fault.

Symptom

Rough Idle or Shaking? We Find the Cause

Is your car shaking at idle, or running rough when you stop at a light? A rough idle usually points to a misfire, but many things cause that. We test to confirm which cylinder and why before recommending parts, and if a check engine light is on we read that too. Serving Lynchburg VA and Forest.
