[V8] Engine miss and no power

[Jeff Goldberg]

Hi All,

Car sat for 10 days, started right up and idled good, but terrible miss and
no power when I tried to apply throttle.  I let it idle for a few minutes
and it started to miss at idle, then stalled.  I left it for a couple of
hours and got the same symptoms,  started right up and idled fine, but no
power.  I heard it backfire into the intake manifold a couple of times when
I tried to apply throttle.  I have had it miss on a cold start a couple of
times in the past, but it has always cleared up in less than a minute.

I pulled the codes with the engine not running and get 2111 RPM sensor.  Is
it normal to get 2111 when pulling codes with the engine off?  I'll try to
pull them with it running...if it will idle long enough.

Any ideas on what to look for?
