CEL on idle speed - P0507 Idle Air Control

Hi guys,

The CEL came on Friday. I didnt have a scanner at that point and the light wasnt blinking so waited till the week started. Saturday it went away and was off all through sunday as well. This morning, I started the car and saw a bit of smoke in the back. It wasnt the first time I started it this morning either, so am a little confused. Took it to BigO (changing tires anyway) and had them check out the issue with their scanner.

Error Code P0507 - Idle air control - idle speed too high.

BigO reset the CEL for now. I havent noticed any particular high idle speed, but feels a bit odd when I start out of 1st. I dont know if its the engine or if its just me being paranoid..

Any suggestions on how I should proceed?

Greatly appreciated ..

SuKr

Many times when the weather changes the ECU will read some of the data differently and will generate a CEL.
If you don't do anything, it should reset itself when the parameters are back to normal.
If it doesn't, you may have a dirty idle controller.
Happy Boxstering,
Pedro

P0507 Idle Air Control at Stop – Above Limit
Your car is egas so you are looking at the wrong P0507 fault report.

Chances are you have a dirty throttle butterfly. Buy some throttle body cleaner and clean the throttle body and butterfly well.

Pleasanton/Dublin area indie shop??

Thanks guys,

I will check it out. It came back on today after a bit. Any recommendations for a indie porsche shop in Pleasanton/Dublin area?

I saw the recommendation list and found:

Kahlers Werkstatt in Dublin
Conversion Techniques and Bauer in Oakland. All of them are do-able.

Might just try out Kahlers this time around, should be a small job and can evaluate them too They have good reviews already though..

Problem and correction

Hi guys,

Thanks for all the info. I have been reading some forums and am pretty sure that ppbon and Loren are on the money ..

Here are a couple of links if people want some detailed info on this DIY

http://euroautoforums.com/forums/ind...showtopic=1351
http://www.renntech.org/forums/index...throttle+body\

The first link is for a 996, but it should be valid in principle to the Boxster as well I suppose.

So now the only problem is getting to work I stay in an apartment and havent gotten into boxstering yet. Dont have the tools either I can probably stop by work (nothing to do with automotive stuff) but as a mech engg I might have the tools to try it. Am a little hesitant as if I screw up and cant get the car started, might be in a fix .. hehe .. Will let you all know how it went ..

Thanks again..

SuKr

Usually you get gobs of smoke with a bad AOS.

AOS is MSRP $97.19 -- so the rest must be labor.
Porsche "Book Time" is under 2 hours.
Sounds a little padded.
