[Shotimes] Using a lot of fuel and running rough

These are your KOER test results...you didn't run the test right.  These
are all codes spit out because a series of events weren't accomplished
properly during the DRT (dynamic response test).  You know the part
where you have 10 seconds to turn the wheel lock-to-lock, hit your O/D
button, momentarily go full throttle, hit the brakes, etc.  Something
went awry there.

Try it again.  It can be tricky to accomplish everything, but it does
work.

When you have a "real" code let us know.

Good luck,

Hi all.  Hope someone can help so I don't have to spend a ton of money
again.  My '93 3.2L ATX has been running rough lately.  A while ago it
wouldn't stay running and I replaced the IAB valve on it.  That sort of
fixed the cold running but it still does it occasionally.  Also, it's
been running really rough and is getting horrible gas mileage (used to
be around 20, now down to about 14).  I ran the codes and got the
following:
129- Insufficient MAF change during dynamic response test
167- Insufficient throttle position change during dynamic response test
536- Brake on/off circuit failure/not activated
521- Power steering pressure sensor/switch did not change
632- Transmission control switch circuit did not change state
411- Can't control RPM during low RPM check (the car stalled during the
test)

I know they all aren't contributing to the main problem, but could some
of them be?  Also, what do the other codes mean?  Sometimes my brakes
will kind of go stiff on me but I just figured they needed to be bled.

Anyway, I know this is a lot.  Hope someone can help.  Thanks in
advance.
