"Check Engine Light

[DezRacer]

I need help! I tried to get my 92 4x4 smogged this week, the shop said because my "check engine light" was lite I could not pass, everything else passed. This motor is origional with322,000 miles.
Has anyone had this problem??
Thanks

When the check engine light is on, that is the computer's (PCM) way of telling that it can see a problem. The EEC-IV system has built in diagnostic tests to help you find the problem. The "quick-test" (aka pulling codes) is simple and requires only a short piece of wire to perform, and the codes are output as flashes of the check engine light. Personally, I like to use a voltmeter instead of the check engine light for code output, but it's not necessary to run the test. If you want to do it yourself, there are instructions at www.dalidesign.com/hbook/eectest.html .
