Engine power reduced can have alot of reasons for coming on... something is out of range or not working properly and thr computer has limited engine power... u need to scan it and find any codes

Clean your throttle body for starters. Unhook fuses #10 and #28 before you remove the throttle body to clean it.

    My son let my car run out of gas and it started skipping, he didn't tell me it ran out of gas so I thought it was the plugs. I changed all the plugs but when I went to crank it it ran for 5 seconds...
