Hello everyone,

I recently purchased a 2003 boxster w/ 65k miles in very good condition.

I noticed that the CEL comes on when the engine is pushed near redline. The code is cylinder 1 misfire. First thing I did was change the sparkplugs. Then I switched the ignition coil from cylinder 1 to cylinder 2. Still having the same problem.

Any suggestions are appreciated
