I have a stalling issue which I am convinced is an electrical issue rather than mechanical. I'd like to get a recommendation on a tech in the Chicago area who can diagnostically solve the issue. We've been fighting this for a year with no success.

I'd recommend two round trip plane tickets LAX->ORD. One for Bruce7 and the other for his oscilloscopes.

Ernie,
Not the Chicago area, but you might want to talk to Loren at http://www.systemsc.com
Cheers,

Give Brian at Midwest Eurosport a call: 630-595-5577. Or call George, at their Autobahn Country Club location. I think his number is 815-727-5577.

Brian has looked at the car and had no recommendations other than to drive it.

Thanks Paul. I'll reach out to Loren; but, I think that whomever figures it out will need the car to do that.

Is there not anyone in the Chicago Region that knows of a capable electronics tech locally?

Ernie - I had a "stutter" issue with my 993 within the last year. Typically, within the first 5-10 minutes of driving, the car would "stutter" and throw a CEL. I don't know if your "stall" is a worse case of my "stutter" but I thought I would respond with my experience.

It seemed to me to be a fuel delivery issue. I first tried a fuel additive. No luck. My current tech is Sol at Perfect Power, Buffalo Grove, IL. The fault code pointed to an injector. Initially the CPU which controls the injectors was suspected (the board was found to be cracked for some unknown reason). The CPU was replaced with a refurbished one. That did not resolve the problem. Head scratching time. Then, one of the techs observed an impedance issue within the engine harness. Apparently, somewhere within the engine harness was a frayed, cracked wire that controlled the injector. Sol implemented an effective work-around (the engine harness was not replaced - that would have been $$ I was told) and the car has been fine since.

So, since you mentioned "stall" with "electrical" I thought I would offer my experience.

Thanks for your kind response. Sol also had my car.......for over two months and had not been able to find the cause of stalling..

Check out Chicago Performance and Tuning (CPT) in Melrose Park. Al and his team really know their stuff and have a lot of experience with air cooled Porsche's.
