I have a Grand Marquis with the police interceptor engine. It will crank and idle fine, but will not accelerate when I press the gas pedal.

Good evening.

The fly by wire system has a pedal sensor and the throttle position sensor are the controls.

Is the check engine light on?

Hello DPRINCE07,

If you decide you would like to conduct the scan yourself here is a link to an article from this site that features written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com
