2002 Grand Prix GT
3800 6 cylinder
Diagnostics done at GM dealership
Done to repair = bought new battery
tech = KK
question = My car will sometimes die on the first startup and then
crank on the second try. The rpm gauge will jump to about 1500 rpm's, then
drop to zero and then level off at about 900 rpm's. It has also started
to die when you put it in park and it has died when you turn the air
conditioner off. We took it and had a diagnostics ran but they could not
find anything. We also have the abs and trac light on and we had that
repaired about a year ago or so we thought. We recently moved to Texas
from South Dakota also and I know heat can cause more problems. So
that is my question. What causes this?
JK:
Couple of things i would suggest. Clean the throttle body bore, plate, idle air
control valve(IAC) and its bore. If these things have carbon on/in them, it will
cause the problems you describe. A leaking fuel pressure regulator can also
cause this. When they leak, fuel enters its vacuum hose, and can also cause
these problems. Let me know what you find, KK

JK:
There are several reasons for this code.
You may have a blown fuse(s), a bad A.I.R. pump, or a sticking diverter valve.
Be sure to check all the fuses in the underhood fuse box. If any are blown, the pump may be faulty
and blew a fuse. Sometimes they will even burn the wiring harness for the pump.
If this is not the case, a diverter valve may be sticking and not alowing the pump air flow to enter the
exhaust to clean it up.
