2015 Cooper S Roadster. N18 engine.
Coming out of a high-speed corner in third, floored it, just about to shift to 4th, engine misfires, CEL comes on, goes into limp mode.

several codes all related to “Combustion Misfires”:
2EFE
2F00
2EE0
2EE7
2F02
2EED
2EE1
2EEF

Where do I start looking?

The fault codes seem to indicate misfires in cylinder 2 and cylinder 4 and to suggest testing of the fuel supply, ignition, air supply, engine cooling, and engine mechanics.

 

Wow! That narrows it down. 🤣

 

Do you have a scan tool that reads live data? If so, you can start by checking fuel pressure from the HPFP and the engine coolant temperature.

You can also swap spark plugs and coils between cylinders; verify the engine mechanical timing; and check for clogged fuel injectors.

 

Yes. HPFP runs around 1100 at idle & around 1700 while running. Coolant temp stays around 200°f. I was gonna throw a set of coils & plugs on it since it’s never been done as far as I can tell. 90k miles on the car. I’ll look into the timing & injectors. Thanks.

 

Sounds like a good plan.

I'm hoping plugs and coils are the solution.

 

Just for giggles....check your oil.

 

Oil looks good & clear. No coolant in it.
Might have a slight fuel smell. Hard for me to tell. My sniffer is not so good anymore. 🙃

 

^Wouldn't be surprising or unexpected given the engine misfiring.

 

Installed a new set of plugs and coil packs. Cleared codes and went for a test drive.
Runs like new again !

Thanks to everyone who responded. Cheers!

 

I'd say keep an eye on it.
I did new coils/plugs back in Oct 24 & just had my misfire return.
