Question about 1998 Porsche Boxster
1998 boxter runs perfect at idle ,,when rpm is increased engine starts too missfire and wont reach full power ,,,have changed the spark plugs and the air filer ,this has made no difference...
It might be injectors and/or fuel filter clogged.
Try to use injector cleaner (ask for recommended heavy duty in auto store) also I would check maf sensor.
Also misfiring/backfiring is a sigm of worn/damaged distributor cap/wiring
Please kindly let me know if this info was usefull/useless for you or you need more info
