I would invest in a durametric and see what values you are getting for timing or codes for misfires etc.
A regular ODBII scanner won't show all the other good Porsche codes.

With this little info it would be hard to know where to start and just replacing everything till you get the faulty part could be costly on a Porsche.

IF it is misfiring it could be coil packs, Crank position sensor, spark wires on on wrong plugs, sliipped timing chain, air leaks, MAF, throttle position sensor, wiring fault(broken or grounded or no ground), loose sensor/computer connector etc
