1997 993 Misfire, no. 2 cylinder


Vehicle Information: Year: 1997; Body Type: Cabriolet; Total Mileage: 52000;

I recently purchased a 993. At cold start it idles fine. Once it is warmed up (10 minutes or so) it misses intermittently at idle. Under power there appears to be no misfire. Sometimes the check engine light comes on, but it has cleared itself on a few occasions after sitting a few days, which I don't understand. The codes show a misfire at no. 2 cylinder. The spark plugs and fuel filter were changed at 50K, but the plug wires were not. Do these engines need plug wires at 52K, or do I have a clogged injector? Any ideas?Also, I do not have the factory maintanance booklet for the car. Do you have a printout of the reccommended scheduled maintance program?
