Just got a P0303 again. 61,000 miles. Local garage checked and reset it for free. They asked if I had changed the spark plugs recently. Yes, but 4 months and 2000 miles ago, and the car has been running fine (drove it for 2 days with the CEL and didn't notice anything abnormal). Just a random misfire I guess ...
