Possibly a bad maf

[MNBoxster]

Hi,

Pull the MAF and try cleaning it before spending $$$. If it works, at least you've bought some time.

You might be getting some detonation, use only the best gas. Going to a colder plug is OK if you can find one in the proper range. Too cold and you'll foul the plugs. Forget the irridiums, they're a marketing gimmick at a premium price, stick with OEM Bosch or Beru...

Happy Motoring!... Jim'99

Hi,
I recently had my MAF go bad.The car ran real bad on startup in the morning. It accelerated horribly and was just slow.I got the codes read at autozone and it said oxygen sensors,well it was the MAF and not the oxygen sensors to make a long story short. To figure out if that is your problem,just disconnect the wire for the MAF and it will put the computer into default mode,your car will run great if that's the problem.By the way,don't buy the bosch universal oxygen sensors if you ever need to replace any of them,they don't work .

I wondered anbout those cheap universal 02 sensors. I have a couple of good 02 sensors from another car and dont see why they couldnt be used if I could figure out the wires.

Yes,I thought they would work great. I bought them off the internet for a good price and looked at the diagrams in my porsche service book and figured out the wires.(2 whites,1black,and a grey).After hooking them up,the car ran MUCH worse.I then spoke with a mechanic friend of mine and he said that most of the universal sensors will not work correctly on high end cars.Well,atleast I tried...

Frank,
It worked! I pulled the harness off the maf sensor and the car started right up cold with no stumble. I kept it out of boost and drove it home with no issues. That was a great idea unplugging the maf! It kept the values set and allowed me to eliminate the maf from the equation, Thanks!
