I have a 2003 360 spider and today the car hesitated while accelerating transiently It is driving fine now but the yellow engine/emission failure light came on and has stayed on will take it to dealer next week but was wondering if those much more knowledgeable than I had any thoughts thanks
you will need to get ahold of an obd2 reader.. have them at autozone, plug it in below steering wheel. will give you a code as to what it might have been. possibly a misfire, possibly something else. worst case you need to chat with your mechanic..
