Hi,

I had to pull onto a busy motorway from a service station so put my foot down to get out. As I did it a warning came up on the Idrive "Drivetrain" and the engine light was flashing.

I managed to get home slowly as it was running rough and was limiting the power/torque or whatever the limp home mode does. It was rattling and wobbling too. Got the codes up on my cheap ODB and it was "p0304 Cylinder 4 misfire".

I know there's a lot of posts about this code on here but before I start buying coils and plugs I thought id check if it could be anything else due to the fact I was accelerating hard.

Has anybody else had this when you put your foot down? Maybe it was just coincidence and the plugs/coils needed changing anyway. Hoping it's not something more pricey. I let it sit for an hour and tried driving it, but its still misfiring.
