OK,
The X idles fine but has noticeable hesitation when cold for the first half dozen accelerations from stops until warmed up. Then, on the highway while crusing if I slow down to the 50-55 MPH range and about 1500 RPMs she will definitely hesitate until the RPMs get back up there. Mileage is down a bit too which leads me to the FPR, which was replaced at the stealer in 2000. Is it time for a new one and O2 sensor?
Other than that everything is normal...
