99 Oldsmobile Silhouette starts but then dies


Asked by Oct 07, 2016 at 07:57 PM about the 1999 Oldsmobile Silhouette 4 Dr GS Passenger Van

Question type: Maintenance & Repair

My 99 Silhouette died on Monday and idk what the
issue is. Had been driving fine. At one point rhe
check engine light had come on. Got it checked at
Auto Zone. Was told the code it was giving was for
the MAP sensor. Light went off and never came
back on. Passed emissions. Monday was driving
fine. Stopped at a store. When I came out I started
ot (started fine) sat there for a minute and all the
sudden the engine started revving like I was
pressing on the gas. Turned it off, sat a few mins,
turned back on, no problems. Drive away and when
I slowed down it stalled and died. Started back up,
drove again, and when I slowed down it stalped
and died and this time wouldn't stay started. It
starts but then dies quickly out. Fuel pump is
working and it obviously has gas. Help!

Have you driven it today? Has it died ?


Not today because this happened Monday. It won't stay on long enough to drive it. I started it today and it did the same thing. It starts fine but then dies after 5 seconds.


Sounds like the IAC (Idle Air Control) valve is bad. HTH. -Jim


Thank you for at least giving me a starting point!
