Hi

I have an issue with high revs on startup on my MR200 facelift. I had a flat battery after stupidly leaving my lights on at work. Upon starting it goes up to 2k then drops slowly to around 1k without any popping from the exhaust. Odd thing is if I depress the clutch it drops fast like it used to and the exhaust pops. Any ideas? I tried disconnecting the battery and removing fuses to reset the KAM, left it idling for 10 minutes then turned off and then started it again and took it for a gentle drive

Thanks
