I'll check it tomorrow! THANKS! It never happened until I removed the cats though...hmmm.

Just seems to me that when you take the time to specify a name of a product in your post about a problem, then you are tying the problem to that named product (otherwise why specify?). In any case have you checked to see if the post O2's are grounded?

The first time you restart the engine after disconnecting the battery the throttle must be fully closed. The ECU selects the smallest opening angle of the throttle as the idle position and the ECU learns this position on the first start-up. On previous models there was an actual idle switch, the 993 did away with that and uses only a throttle position sensor.

If Adam had brought his 993 into a shop he would have done the exact same thing and this place should be no different. He's not a mechanic, he has a running problem and the problem only started after he installed your product. The two might not be related but for the purpose of diagnosing this and any running problem it is important to have as much background information as possible. You have no idea how many times when describing a running problem that people forget to mention they just installed something themselves or had a shop do some work, even when you ask them. Everyone ends up running around in circles. If the fault is not related to your product it will come out in this thread and your product will get some positive exposure.

Yeah, don't worry about it Chris. Like you, I thought the original post was assigning blame to DACH's design, but I'm sure anyone interested in bypass pipes who's reading this thread understands that this is an issue with all pipes, not just DACH. Your willingness to help solve the issue will overcome any other perceptions.

That's where I'm at with it. I want to help the guy, but don't see why THE name has to be used......I mean a by pass is a by pass, a mod like any other.....does a name need to enter into it? I just took it a little personal I guess.....I mean its not like David (DA) and I (CH).... don't spend countless hours making these in our off time.....away from the family and honey do's or anything

I put the name in the thread to eliminate ALL variables, and I was SURE that if I didn't put the name, that someone would later ask me what brand they were to help diagnose. Chris, CALL me if you have any issues with my conduct. We can discuss. NOW Let me REPHRASE:
I have eliminated teh cats from my car...now it stalls. They are a generic brand...no idea where I got them. How can I make my car stop stalling?

Ritalin anyone? (again)...lol!

Adam...

I don't think your cat by pass pipe is causing your car to stall.

Have you replaced your DME Relay ? IIRC, the DME powers the fuel pump. As the car gets hot, so too will the relay and it may be shorting out intermittently ....causing the fuel pump to act up and affect fuel pressure..ie; poor idling and stalling.

FWIW, I've had my DACH cat by pass for over 3 weeks now and 500 miles. I've had not one driveability issue with the car. It pulls strong and idles perfectly.

Oh...and to say you weren't blaming Chris' by pass pipes as the reason your car was stalling is ridiculous. Your Post Topic states " DACH Catless X-Pipes:Stalling" Not much room for interpretation there pal.....

adams993

I DO NOT blame chris' pipes. I love the sound and finish of the pipes. I simply have never had my car stall until I removed the cats....and wanted you gys to help me diagnose this problem....it would be if the same if I had some coilover issues and wanted help, but didn't supply the brand of the coilovers which were giving me problems.....I'll look into the DME.
