Hi there. Since the Check Engine Light is on then the computer needs to be scanned for codes first. I usually do this before going any further with it. This can be caused by any number of sensors on the engine or it can be a failing throttle body. Both are common issues. The most common problem I see on this vehicle is the ignition switch failing. This should be tested also if the scan does not show anything.
