After doing a visual inspection and checking the air injection pump (all good) I've decided to follow Ed's plan and just change both the elec ($25) and air ($188) valves. Can anyone tell me the best way to get access to them both? I've had a look down through the top access but can't see an easy way to get to them. I've got the Bentley Service Manual but it only seems to have a system description, no maintenance instructions.

Thanks,

I'm sure this has been covered somewhere, and you've probably tried it, but my .02 would be that it sounds like a vaccum leak. Porsches are weird about that, in that most of the time they "cope" and still run somewhat normal unless its a big leak.

Get a handheld propane tank (small torch, open the valve, but don't light it) and wave it slowly through your engine compartment. Chances are you will find a small leak somewhere (you'll hear it rev-up a little).

Just a thought, been down that road and sometimes things like this are hard to diagnose given the fact that there are a lot of hidden areas such as intake manifold runners and AOS boots.

Good luck, and keep us posted of your findings.

Does anyone know where I can get detailed instructions on removing the air intake manifold so i can get to the two valves mentioned in my previous post?

Did anyone ever replace the valve and switch yet? Did you happen to take pics and come up with the DIY? This still may be a Fall project for me.
Thanks

I'm in the same boat. pump seems to be working. but throwing the codes. thought I might go this route too.
please post a follow up on what's involved in replacing the the parts mentioned. for the cost, it seems like a logical thing to try....
