Scoot died today . Fuel injection.

First topic message reminder :

I have a power CommanderIII on the S'wing since last winter.
For the last couple of weeks , at low idle it would serge then be ok (rpm Drop).
then this week when idling it sounded like it was running on one clyinder at idle once in a while.
I would rev it and it shouddered like in was not getting fuel or was loaded too rich.

One time when I restarted it , there was a puff of white smoke. (Too rich?)

Over 3k rpm it runs great.

Tonight I was comming home and it got worse and finally died when I was at 3k rpm or lower. And The red light to the left of the yellow V belt light came on and started blinkin. I turned the key off then on and it restarted. Got it home.

Tomorrow Diagnostics:
Check plugs

three things come to mind
1. the Power commander is bad in the lower rpm range.
2. an Injector is stuck/hanging.
3. Fuel Regulator is bad.

I will keep everyone informed as things unfold.

MaxB (got to read the service manual tonight)

It could be it happened in the original MFG process and never caught, crap happens and you got to be final QA.
