Subject:Help - Power loss above 2500 RPM once engine warms up
From:Joel Cort

Hi all,

I'm sort of stranded but made it home to my garage.

Here is what I've been experiencing the past two days and I'm
throwing this out to the expertise of the list.  I did check the
archives but did not find my specific issues.

My 89 Syncro Westy runs fine, idles fine, starts on 1/4 turn.
It has lots of normal power (for the 2.1l engine) and I can drive
about 5 miles. At about that distance, the engine finally gets to
normal operating temp. with the white needle just teatering above the
red LED on the gauge.
From that point on the van idles fine but if I drive off I cannot get
any power above 2500 rpm. I cannot get going more than about 30 mph.

I've put my DarrellTool on to test all the sensors and every one
responds OK from what I can tell.
The Temp1, TempII and AFM all respond. LEDs respond.  The only goofy
one was that darn O2 reading. The O2 fluctuates from -0 but for the
most part of the reading was around .70 at norm. operating temp.
From past experience I tried unplugging the O2 green wire but this
did nothing to alleviate the problem.  It is still there and real. So
for whatever the O2 is sending, this is not the problem with the
power loss.

Other than that the climate has been in the 40s with drizzling rain
so relatively high humidity.  I've checked the sensor connections and
cleaned up what I could but still nothing to change the problem.

So fellow VW engineers I solicit any help on where to look for the
cause of this problem (other than living in Rochester NY).

Thanks for any help.  Please email me at joel.cort@usa.xerox.com as
well.

Thank you all.
Joel
