Check Engine Light/Code interpretation
I need help with an economical way to solve some faults that my mechanic retrieved from my OBD:
#80=secondary air injection system cylinder (1-3)
#208= secondary air injection system cylinder (4-6)
#95= shutoff valve, activated charcoal filter (function)
Any help on how to solve these issues to shut off the check engine light would be greatly appreciated.
It is a 1998 993 coupe C2S with 115K miles. Engine has never been opened (and would like to keep it that way).

Yes dentist Daryl,
In the admin section at the top of the 993 forum, read the article Recap of the SAI system.
Or
Call Steve Weiner of Rennsport Systems for a bypass to the system.

Listing both banks may suggest the need to replace the check valve or review the air pump or the wires to it.

Step 1, if need be Step 2. Done.
+1. Agreed.
Replace the SAI "check valve" as an initial step.... Its located behind the air cleaner box assembly.
The soft metal base of SAI valve itself corrodes, leaking air pressure, more and more. Over time if not serviced (new valve) its the valve's mechanical failure as the "Check Engine" source; codes etc.
Step 1. Service/replace the SAI systems check valve and clear the ODB-II check engine light,,,, then drive. For many 993 owner's a new check valve does the trick. For others its on to Step 2. The clogged SAI system galley/ports in the cylinder heads require a strenuous clearing.
The valve part # Check valve 993-113-250-03 ..$75.00 and Seal Ring 900.123.011.30 ..$1.00

There is no such company/product...The responder has a tendency to capitalize words for no apparent reason...
He is referring to you doing it yourself (DIY) or have a mechanic who will use the solutions and cables mentioned in the, "Recap of the SAI System" for cleaning the SAI ports.
Yes, you will need to replace the aformentioned check valve, but if the ports are clogged, changing the valve will have no effect on the SAI related CEL that is being thrown...

Guys,
Cut the newbie some slack. Having multiple CELs can be very intimidating to a new 993 owner. I would bet that when some of you first got a cel you freaked a little.
Doc Darryl, please look at the Pinned SAI THREAD. Because you are a dentist You have the skill set to do some things. Keep asking questions and take it step by step.

You 993 gave you a happy new year gift, huh?
I sent you a text.
You're going to do surgery with piano wire and a pool of techron. Probably some dental tools, too.

I do however, see where you provided nothing additional other than to reiterate that which I had already stated. (for post count purposes?)
Daryl, again, the sai recap admin post at the top of the 993 forum, as previously stated...Lots of information, links, photos and processes documented there.
Engine has never been opened (and would like to keep it that way).
I dont know what your documentation looks like with regards to maintenence documentation on your 115k mi., 993; but there are some worth while items to tend to while you're in there if there are no records of replacement...
I'm sure forum members will be happy to chime in on such items.

My advice would be do as I did. I took my car to a guy in SoCal who was trained to work on 993s at the Porsche Factory.
Peter at StuttCar Service in Pasadena. Now I did have the top end rebuilt when I got a nice bonus a few years ago. But since I have been going to Peter I have passed California Smog the last 2 times, last 4 years for the first time with nothing more than a precautionary reset the codes, running Chevron Super all the time, and a 30 minute warm up. No lighting a tyre on fire and dancing around it naked on a full moon to appease the emission gods or stealer antics. But what do I know, I just want to drive my 993. And Peter has been instrumental in my enjoyment of the car. There are others in my part of the world who swear by Peter.
But apparently, you guys know more about it.

Liquid Solution by Independant Mechanic
The Liquid Cleaning Solution was offered by a firm in New Jersey named bodymotion - see link
http://www.bodymotion.com/check_engine_light.asp
As recomended as Step 1 - M. Schneider suggested DIY – “Do It Yourself” - Install New / change the SAI Check Valve & remember to add a washer to assist or Ease the future removal of the check valve. Some members prefer to change at 60,000 some every 30,000 Miles.
As described herein this Post by bruce7 – link - Another Excellent write up by bruce7 !!
https://rennlist.com/forums/993-foru...eck-valve.html
The liquid solution I think is run through the injectors - If not mistaken - but I have not done this and am not familiar. I know of a Porsche Dealer that offers this service although I prefer and Recomend Independant Mechanics - Entrepreneur Specialists on 993 P cars as our cars are 20 years old now and not all dealers have specialists on staff for the 993
.NEW S.A.I. CHECK VALVE # 993-113 250 – 03 with new SEAL RING part # 993 111 195 (22MM washer)
Step 2 - change TT Vacuum line or Air Distributer 993-110-573-00 a cheapee fix - unless recently changed? Review your Service Records>?
Next one of my old posts “Calling All SAI Port Drillers - Suggestions? Help ?”
Here is the link if u wish to know what was required / involved. I was able to do the job Thanks to All Rennlisters!
https://rennlist.com/forums/993-foru...ions-help.html
Now correcting issues with the SAi system is not always a simple process. There are many parts so a smoke test to find leeks may be required. If u complete step 1 and 2 - the tt pipe then do a reset of the cel codes and test again many here will chime in to assist you. After I drilled there are No More CEL’s for me – it worked
Now you have an overview of the tasks and necessary tools to do the work that is likely required.
First, before u start, I would look into the Service Records you hopefully have to inquire when the sai check valve was last changed.
As illluded to earlier by "nine9six" check to see when the last major service was completed (usually 30,000 Miles) re: changing the spark plugs and spark plug wires and additionally go through your records to determine if or when the distributor caps and rotors were last changed.
A Good P car mechanic, a 993 specialist can help you out - if you decide not to diy this.
I am sure your local owners will jump in with recomendations for a good specialist once we know where you are located.

For your questioning why I am chapped about cel's please remember I live in SoCal where, at registration time, a cel causes real concern. Let me suggest you read this thread to get some idea of dealing with smog in California.
https://rennlist.com/forums/993-foru...appy-smog.html
As for the lack of civility that has crept into this forum may I recommend this thread
https://rennlist.com/forums/993-foru...new-owner.html
The OP's first post, no welcome just look it up. Miss congeniality nine96 is not.
Or your comments in this thread:
https://rennlist.com/forums/993-foru...-stole-it.html
You disagreed with OP without giving your reasons until promped. Way to promote discourse. But please tell us your bona fides. Do you have a shop that works on 993s? Is there more than one Indy Porsche shop with in 15 minutes of your residence? Does your car ever go to a shop? Please let us know your expertise.
For the record my hood has several competent shops so I CHOOSE to let the experts take care of my car. I sleep better and wifey does not question what I do. A win / win.
This forum has digressed to a point where I wonder "why bother".
So good buddy lighten up. Be cordial, there is more than one way to drive and fix a 993 so do not act like a snot if my way is not your way.
Like me you are not an expert on the 993. All I do is report what has been my experience and methods.
And for the record I am of the drive the car hard and frequently rather than baby only on weekends where no rain is in the forecast. I drove the 993 on the harder tours during the 2013 Escape. No break downs, no cel's, just a whole lot of fun.
