I have a feeling my catalyst are failing or blocked on my R36, as previous issues with misfire, performance and exhaust note change.

At what temperatures are normal for cats on both banks? Done a...

Im from the west midlands, Yeh ive heard of them, the do carbon cleaning but not wallnut blasting i think, but I one of the reviews on google put me off taking to them.

No Ive tried different gap on them still the same.

Not as yet but in search in finding a company to do it properly. my concern is why it misfires on the ngk plugs not the bosch?

Thanks very much for your swift response :toast:, the coolant hose do i need to disconnect the hose from the rad or just where the hose is mounted to?

Need to replace my radiator fans on my R36 , not sure the best way to remove it, as space looks restricted don't want to remove stuff if not needed for access.

Update, been to a specialist, they diagnosed the issue , long story short it the brake booster. leaking as its hissing on idle but goes away when brake pedal is pressed.

How easy are these to...

Thanks Lucas, are the part numbers exactly the same for both sensors?

Car came back from the specialist, they stating the knock sensor is really high of 16v and should not be higher than 2v max, was told to suggest changing that, before they think about removing the...
