Loaner Dme?

[ma702tt]

This is a follow-up to my previous post

"Consistent intermittent brief engine shutoff"

Is there anyone out there that would be willing to lend me a DME for a 964 I could place in my car and see if it works in my car so I can confirm mine is bad?

Thanks,

Matt

Matt as I said - I have one. Contact me by Email 3.6(at)cox.net so we can work something out. What model number is yours? Is your car a stick or a tiptronic?

BTW, reading you post of the symptoms it really sounds like an intermittent wiring failure rather than the DME. I wonder what diagnostics the shop has done.

Last year I had something very similar with my 3.6 conversion. The car would stall during normal HW-cruising. All of a sudden it lost all power and then came back to life a second later just when I thought it was time to pull over. When I hooked up the hammer (Bosch tester) during driving it would show that the O2 signal went to 0.00 Volts whenever this condition happened. It turned out to be the O2 sensor connector. It made bad contact. Unplugging and re-plugging it fixed it.

What surprised me was that the engine felt like it had no spark. That's how bad the poor O2 signal messed up the ride. Sometimes there were faults stored in the DME - sometimes not. I guess with the O2 sensor it depends on how long the signal goes away. If it is less than a second it suffices to screw driveability but not long enough to trigger an OPEN fault in the DME.
