Hello, my name is***** you tell me if the computer has been scanned for codes?

No, I have not taken the vehicle into a shop or dealer. I'm trying to fix this without a huge expenses, But if it's necessary that I should, then I guess it's come down to that.

Thanks for getting back with me. Since the check engine light is on the best thing to do would be to have the computer scanned for codes. Most auto parts stores will do this for free. If you have this done and bring me the codes it will help to diagnose the problem. Most of the time this is caused by either a vacuum leak or an issue with the variable valve timing solenoid.
