2003 Ford Taurus SES fuel pressure regulator

Car lurches at 60+ mph. Rpm goes from 20 to 30rpm.
Suspect defective fuel pressure regulator or vacuum line. This does not occur at laower or idle speeds.
Any suggestions welcomed.

The FPR is electronic, and works along with the FDM in the trunk to adjust pump speed to control pressure. Use a scan tool that wil lread the fuel pressure PID to see what the FP is to eliminate the FPR as the problem, which I doubt it is.

Do you mean goes from 2000 to 3000 RPM?? If so, sounds like they tranny is downshifting from OD to 3 for no reason. Suspect a failing VSS>

VSS = Vehicle speed sensor, also known as OSS = Output speed sensor. Tells PCM the cars speed. Located in the pass side of tranny. Known Taurus problem that causes all kinds of tranny shift and slipping issues.

Jeff nailed it! The VSS is probably what is causing this.

I just noticed on a trip this weekend as I went over road dots that my speedometer went all wacky for a second and my transmission did NOT like it. Now i'll have to replace my VSS. That or check the connection and see if it needs cleaning, at that point why not just replace it ?

2003 Ford taurus SES, VSS TSS, OSS

VSS - Variable Speed Sensor
OSS - Output Shaft Speed Sensor
TSS -- TRANSMISSION SHIFTING SOLENOID
I assume that the
VSS, TSS and OSS are the same?

Where are they located on a 2003 Ford taurus 6 cylinder engine?
Wife drives car daily for 5 miles to Gym or grocery store.
The problem of lurching was evident when I began to climb a hill in January 2011. I had the car on Cruise Control (CC). Yesterday, I drove it again on Cruise Control and problem re-appeared. I took it off CC and it kept lurching until we arrived at home -- 13 miles.
Today, I took it to several shops but they were busy and suggested I come back tomorrow.
Problem did not appear while driving around town below 35 MPH.
Mechanic will test while driving tomorrow. He will conduct diagnostic tests.

Here, it's refered to as an OSS (Output Shaft Speed sensor)

See Attachment, Keep in mind you can get to this from the TOP ignore the directions that state to drop the y-pipe.

Ford changed the name of the vss to oss in 2000. Both are the tranny output sensor. Tss (turbine shaft speed sensor) is the tranny input sensor.
