The only major sensor on that older engine is the Throttle Position sensor. Have you tried changing out any parts yet?

You may have a bad EGR valve or EGR vacuum solenoid. Have you removed your PCV to make sure the ball bearing isn't stuck? Have you sprayed any Mass Air Flow cleaner into your MAF sensor?

Have not changed any parts yet. PCV valve is good-- ball is free-sprayed with carb cleaner just to be sure. No MAF- engine is carburated
