THE CHECK ENGINE LIGHT COMES ON WHEN DRI

1986 Jeep Wagoneer

1986 Jeep Wagoneer 6 cyl Four Wheel Drive Automatic 45,000 miles

Yes the miileage is correct.45,000. I know. Amazing huh. Lol

I just bought the jeep a week ago.
I had all the dignostics ran on her, the fluids flushed, changed and filled.
Tune up and oil change as well.
A complete inspection done and everything is great they said. BUT. The Check Engine light comes on when driving at a steady 63-65 MPH on the freeway. She doesn't make any wierd noises, no shaking while in motion, no smoke, just purrs along.
Also when I am stopped at a stoplight and she is idling, she does shake a moderate amount. Is this normal for an older style engine? Could it be a faulty reading or is there something else I should be looking for?

Thanks for the help!

Correct me f I'm worng, but I can't remember if the 86 has fuel injection or a carb. I know the 1987's were injected, but can't remember the 86.

Let me know about that, and also, if they can't get any codes pulled, I would start by checking for vacuum leaks.

Let me know about the other.
