Engine Performance problem
1990 Chevy Lumina 6 cyl Front Wheel Drive Automatic

Engine lopes at idle and does not excelerate properly. I have changed plugs and fuel filter. What should I check next?

Hello, are there any codes? Can you check fuel pressure? As far as the idle, clean the throttle-body, take it off and clean. Check the idle air control system.
