Hi and welcome to 2carpros
1st we need to know what that check engine light code/s is. You might want to check out autozone parts store and get it read for free.
Meanwhile with a repair manual-you can check the fuel pressure, inspect for exhaust system restriction-ruling out the catalytic converter/mufflers and last the throttle postion sensor closed and wide open throttle voltages.
Is there anything else I can do for you?
