the car performance is seems fine, I'm not sure about it. but I feel there is somthing wrong with that low RPMs and that much exhaust emissions, which seems to be caused by misfire.
I'll replace the sparkplugs and see the result.
Tell us if you solve your prob.
MAXI have you changed the plugs already? I have the same problem although mine stays at 600 rpm but does skip every 30 to 45 secs. and Im also planning to do a plug change
