[s-cars] Fault code 2341 continues

[Mike Platt]

Ok problem is getting worse, which may help me solve
it better. I am still at a loss somewhat. I cleared
codes and restarted car. After a short drive, code is
back. 

Car now stumbles/misfires at idle when cold. If I hit
gas it will stall. When car idles for a minute or so
all is fine until the drive starts.

At very light throttle, or full throttle(boost), while
driving there is no misfire. Only at partial throttle
application, just getting into boost possibly. it will
stumble.

I have done this in the past 30k miles: O2 sensor,
plugs, plug connectors,cleaned idle stabilizer,and
just installed an ignition switch last week.

I'm thinking PSO but could be other things. Pulled the
instruction on PSO's from the audifans site and will
go from there.
