Has the check engine light come on and have you scanned the system to see if there are any fault codes setting?

Customer: replied 8 months ago.
The check engine light comes on when I push on the gas hard, but if I don't rev the engine it will not come on. Also, when I push on the gas hard it sounds like something under me is rattling

No I have not gotten it scanned

You are likely dealing with a throttle body issue here but before you do anything else can you get it scanned and get me the fault code and or codes and we can work from there. Most auto parts stores such as auto zone will run a scan for you at no charge. Post back when you have them and we can go from there.
