Hi,

Does anyone have a Porsche 803 MAF that I could try? I have been chasing P1188 and P1189 codes on my 97 M3 track car, and I would rather not spend a few hundred dollars to buy one if mine isn't faulty. LTFTs are negative, so it is currently running rich. I check the fuel pressure, and everything else checks out. Please let me know.

Thanks!
