Re: 2000 oldsmobile Intrigue V6
This could be a # of problems but try these: Remove gas cap and carefully inspect it and the fuel filler neck for small cracks and/or distortion/dirt. Under the hood there is a small green cap which is the test port for the evap system, remove it and check the schrader valve to be sure its tight ( left hand threads!!!). Check all hoses attached to this for cracks/breaks.Other than this a diagnostic will have to be ran with a smoke machine to pin point leaks or valve/switch/solenoid/canister failure.

Hi, The service light is indicating there is a fault code either in the ECM or BCM system. The only way in which this can be switched off is to have these codes checked and cleared in these to control unit with a diagnostic tool.
this light means that a fault has occured in the electronic engine or emission controls of your car, there are over 200 such faults that turn the light on, when the control module turns on the light it sets a fault code in its memory, have this code read to see what system has malfunctuioned.
There are many emission sensors in the car that will make the engine light come ON. Not to mention the big list of trouble codes for the engine light.
Best way to find out what's going on engine light is to have an auto-parts store hook up a engine code reader and tell you what the code means and the problem. Most auto-part store will do this for free.
without knowing the trouble code that is set in memory anytime the check engine light comes on there is no way to know the problem or if there is a fix under any type of recall, there are over 200 fault codes poss in this system, have it tested for which code turned the light on.
The MIL light AKA service engine soon light comes on to warn of a malfunction in the emission control system or a problem with electronic engine controls like fuel control, there will be one or more trouble codes stored in the PCM (powertrain control module) to show what system or sensor has an issue/problem, take the car to any Kragen Auto, Auto Zone or other chain parts store and they will test it for free, write down the trouble code or code's and post them back on this same thread for me to look at, then we will have some info on what to fix to get the light to go out, also have them reset the light when they test it, it will come back on in a few days, but maybe we can fix it before then, OK?
