Do you have a flashing EML light?

Have you had it read and it’s showing P0301, P0303, P0303, P0304? If so I might be able to help

If you have P0300 or something else, sorry please try asking the forum.

I can’t promise a fix, but it may help point in the right direction.

One day on my daily commute, about 5 miles, I had no issues at all. I parked up and sat with the engine idling for 5 minutes. Suddenly the engine stuttered and the EML started flashing.

Luckily I have a code reader, so plugged it in and came up with the error P0303 (Cylinder 3 misfire). In basic terms it means the ECU has detected a fault on Cylinder 3 and has shut it down to prevent damage.

It essentially means either, spark plug fault, coil fault, fueling fault, manifold leak or ECU fault.

So here’s for the diagnostic...

Switch the coil pack from the faulty cylinder to another cylinder.

What does this mean?

If the error code moves from the faulty cylinder to the new cylinder you’ve moved the pack to, it’s likely the coil that’s failed.

If the error stays on the cylinder you’ve moved the coil from, you have another issue (see list above) I can’t help you any further from here, but you’ve ruled something out.

If the error is on both cylinders... errmmm... help!?! Somethings going wrong
