I was driving along up a hill, and the car stumbled a bit (like a miss), then the SES light came on. The stumble was only for a few seconds... I pulled code 0201, which I think points to an ignition coil? But there is no other code to indicate the cylinder... I tried the ohm measurement check on the coils, but they all looked OK. Has anyone had this happen? If so, did a coil eventually fail, and how long did it take? I am thinking of buying 2 of them (one front and one rear) just in case... The car just passed 60K miles, and other than replacing an O2 sensor and the IAC valve, nothing else has been a problem on the engine...

I had exactly that happen - but my car threw 0102 - MAF.

 

I had a 0201. It happened after I changed the spark plugs and didn't connect one of the coils properly. I would check the wires.
