thats' the "Check Engine Light" as many other cars call it. It means your CCM has thrown a code, and you need to find out what's wrong. HERE is a forum thread detailing how to use your own car's diagnostic mode to find the code. Hope all ends well!

I'll share my experience with "service engine soon"
Bought my 87 in mar of 94, 22,000 mi.Driving home from purchase SES light came on. Car runs great! Never did throw a code!!!!!Changed the ECM (electronic control module)still no fix.Long story short 13 years later SES still blinks on about 40% of the time,someone said there are 2 relays from ECM to dash and they could be faulty.Sold the car with a full explanation of light and 5 attempted diagnostics with no code evident.Pretty flakey electronics I'd say??!!

Just a slight correction
The PCM is module 4. This will be displayed when pins 4 & 12 are connected together which will put it in the diagnostic mode. Once in the diagnostic mode, you can use this website for code identification. This is only for module 4, the PCM (power control module), which is for engine and transmission codes.

Any other step by step info can be obtained on the Forum, or just ask.
