P0310
Cylinder 10 Misfire Detected
Ignition / misfire
Generic OBD-II
High
What it means
P0310 means the ECM has detected misfires specifically on cylinder 10 — fuel isn't burning properly in that cylinder, so the engine runs rough and loses a little power. It's a serious code: sustained misfires dump raw fuel into the exhaust and can overheat and destroy the catalytic converter, especially if the light is flashing.
High
Can I keep driving? Not for long — a flashing check-engine light means an active misfire; drive as little as possible until fixed to protect the catalytic converter.
Common symptoms
What you'll notice
- Check-engine light on (may flash during an active misfire)
- Rough idle, shaking, or stalling
- Reduced power and hesitation on acceleration
- Increased fuel consumption
Common causes
Most likely first
- Faulty ignition coil on cylinder 10Likely
- Worn, fouled, or damaged spark plug on cylinder 10Common
- Clogged or failing fuel injector on cylinder 10Common
- Low compression / mechanical wear in cylinder 10Less often
- ECM fault (rare)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data to confirm the miss is on cylinder 10.
- Swap the coil and plug with an adjacent cylinder and see if the misfire follows the part.
- Replace the worn plug or coil — the most common causes.
- Check the injector for cylinder 10.
- If it persists, run a compression test for mechanical causes. Clear and re-test.

No — especially with a flashing light. An active misfire can quickly damage the catalytic converter.
Can I just clear P0310?+
You can, but it returns within a few drive cycles until the cylinder-10 misfire is repaired.
