check engine light

I've been getting "check engine light" intermittently now for about 2
months. The light comes on for about 2-4 minutes then goes out. The car
runs good but, I did develop sort of a slightly rough idle several months
before this, especially noticeable when A/C is turned on. I called the dealer
and was told they could do nothing until the light stayed on. My car is a 95
SC auto with 94K miles, and has been great. Plugs were changed a couple
of weeks ago with no improvement. Any thoughts or do I wait for a
permanent light?
thanks
 
I guess the Ford dealer didn't want to help you too much. There should be a code stored in the computer whether the light is on all the time or intermittently. The good news is that you can scan your computer in your driveway and all that you need is a jumper wire. Follow this link http://www.dalidesign.com/hbook/eectest.html

It takes you through the diagnosis. Forget about the voltmeter and just jump a wire from the #2 pin to the self test diag pin. Get in the car and turn the key to the "On" position (do not start). Your codes will flash out to you. Good luck.
