Jim,

I had a severe cut out of power that I was chasing down for some time. In my case it was as if I had thrown out a boat anchor when I was hard on the boost and I think high in the rpm range.

In my case my problem went away when I replaced one of the ignition wires (I have switched from the OE coil on plug to the 034 HO DIS coils), upon closer inspection there was a small nick in one of the wires and I'm guessing the spark  jumped to ground. Give your ignition bits a good look.

Regards,

Hey guys,

So nice to have a free-breathing car again!  Now on to the next project.....

I am experiencing some overboost/cut out at all rpm's and it's not necessarily all that consistent.  And it's a complete temporary shutdown, like the ECU is shutting the fuel pump off for a second, not a gradual stumble.  The check engine light will come on every so often while this is happening, then go off after about 2-3 seconds.  Not every time though.  I blinked the codes and got a "2111" which is the RPM/Engine Speed Sensor.  According to the SJM website, I understand that this code can be misguided if the car is not running when blinking codes, but the car was running.  With 140K miles, is it okay to assume that this is my issue?  I have already gone through everything else while trying to track down my lack of boost issues, such as boost leaks, vacuum leaks, fuel pump, wastegate, etc.  My understanding is that if it's a coil or plugs, it will just stumble a bit on the way through the rev range, not a temporary shutdown like I am experiencing.

The sensor is about $100 from Sunset Audi......at 140K miles, seems like it could be the culprit.  Thoughts?

Many thanks to all again.....gotta love the list!

Best regards,
