1984 Chevy Monte Carlo 6 cyl Automatic 110000 miles

The check engine light has come on. Car does not seem to be running any different. What should I be looking for? Does this car have a computer to scan for codes?

If you have a 12 pin data link connector, under the dash, you can check mil codes. You place a jumper wire between the A & B terminals of the datalink connector, turn key just till the dash lites come on, no further. The check engine lite starts flashing, you count the flashes to get the codes. Your lookin for two digit codes. The picture below is just to show location of terminals A & B.
