Vacuum leak and/or stuck throttle. Needing me some help checking it out
Greetings all,
After a wonderful drive back to ATL from DFW where I bought the car I got a CEL for a P-0507 (high idle) and it is usually a stuck throttle plate or a vacuum leak somewhere. The car is idling high (about 1000-1100 rpms). I cleaned the MAF with MAF cleaner just in case. I am good with a wrench but am new to this car (I had a n/a 996 for several years). I want to go out there and check all vacuum connections and remove the intake y-pipe at the throttle body and also check the turbo air hoses. I found a vacuum diagram i think.

Any one have any advice on this? Also I could not find a write up for removing the intake y-pipe after searching. If anyone has any pointers on this it would help alot. Thanks!!!

http://www.6speedonline.com/forums/9...ody-reset.html You could try this.
EDIT: I went through the reset procedure and heard it resetting, drove it around for a bit (motor was still 1/2 warm from previous drive), and same idle at stop. About 1000-1100.

you have to unbolt the airbox and rotate the airbox 120* to the drivers side. to remove. once its out of the way you can see the clops holding the y pipe and the bolts to remove. theres one clamp at the throttle body . lots of vacuum lines and seals around to check. after that do a full boost pressure test when it all back together. testing from the turbos yield the best results

I found the vacuum leak! After I got all the intake off except for the throttle body. I had to do some serious hunting and found it after about an hour. The mount for the "Electric switch−over valve for secondary air" on the drivers side broke and when it let go it pulled out of the vacuum line leaving out of check valve #22. After much effort I was able to dig around and get the hard vacuum line out and I reran the line with some material from Autozone. All is well now and she idles like a champ. Now I need to drive the car for a bit and reset the evap ready and the secondary air ready so I can get her registered. Thanks to all for the help!!!
