I own a 2001 Grand Marquis. It runs a little rough at cruising speed like it is skipping. I have replaced the EGR valve and pressure sensor. The diagnostic code says its the EGR position sensor, but the car doesn't have a EGR position sensor. Could it be the Throttle position Sensor?


Any ideas?


Thanks!Edited by: taudawg

I have a 2001 grand marquis doing the same thing.. skipping at cruise speed.. seems to be worse up hill around 45MPH. I was wondering if you got a good diagnoses on yours?

Thanks
