No Boost Condition - Only Getting 1.0 Bar: 2011.11.12 Update

[Shin Hoshikawa]

Following up on my last email, it appears the 200Q20V passed the boost leak
test.
I can safely tell you this because when I pulled a dip stick, I heard a good
pressure
release.  I haven't had a chance to check the line pressure, but will do
that tomorrow.

Assuming I can confirm the preliminary result tomorrow, I bet the source of
the problem
could be electronic, not mechanical although I still could be wrong.  Now, I
am starting
to really enjoy this troubleshooting.

At this point, all I can tell you for sure is the fault code 4411 is
present.
Do you know for sure if this is related?   I am suspecting it isn't.    Shin

Well, I managed to pull the fault code today for 4411, which appears to
indicate a
faulty fuel injector (or its circuit) for the No. 1 cylinder. Wonder if one
bad injector
or its circuit makes ECU to keep the boost to 1.0 maximum?  Not so sure
about it.

Come to think of it, when I still owned this car in early 2010, it stalled
on me a
couple of times during a very light throttle or coasting.  That could be
caused by
a faulty No. 1 cylinder injector, but I didn't have any problem with turbo
boost then.
So, the next step is to make a home-made boost leak tester.   Stay tuned.
