Engine Performance problem
2000 BMW Z3 6 cyl Two Wheel Drive Automatic 120k miles

thanks in advance for any assistance in solving this problem. Codes p0300, p1580, p0301, p0304. Will not run over 2000 rpm and rough idle. Changed plugs. Cleared codes, changed fuel filter. No difference. It started this one day while I was driving it, but only lasted a minute or two. Now it will do no better at allhave other scanner readings but no standards to relate to. Is there a particular area to concentrate on, such as fuel or injectors or water in the ethanol fuel (premium of course). Any suggestions on where to start would be appreciated.

There is a bulletin for this and it has to do with the part# on the engine wiring harness and the DK motor(the electrically controlled throttle body) The bulletin goes on to explain that replacement of the harness and the DK motor is the solution. Bulletin#12-10-02 describes the parts and their #'s if you repost with the VIN, I can tell you the part #'s
