2003 Taurus-engine revs way over 2000 rpm when in park-vehicle pulls itself along at 45-50mph without touching accelerator-in reverse RPMs seem normal. I just had the oil pan gasket replaced a few days ago-are these things related, is it the TPS, or what?

I have a 2001 Sable .I just recieved a recall letter regarding a cable that sticks and may increase RPMs.It was from FORD and parts and replacement was free at any FORD dealership. rebolser

Could be IAC sensor maybe TPS sensor[RPM].

If the throttle cable is not attached properly to the throttle body or you have a bad motor mount, the throttle cable may be pulling the throttle open as you shift into gear. Open the hood, find the throttle cable on the throttle body. Inspect how it is connected and also how the cable is fastened in the engine comoartnent. Next, watch what happens as someone else starts the truck and puts it into gear. If the engine shifts significantly, check for broken motor mounts. If the throttle cable is misbehaving, correct the installation.

The revs should be around 700- 900 rpm while in neutral. Revs about 2 (2000 rpm) is absolutely abnormal, and of course the vehicle will **** with any gear change. Furthermore, continued operation of the car in this condition will damage the transmission. Seems like the idle sensor, MAP sensor or other part is working incorrectly. Take vehicle to a shop for a scan of the computer and repair, in order to save the VERY costly transmission.

Hi Tom your vehicle is equipped with a Rev limiter it will not allow you to rev the engine above 4000 with the trans in park; as for the first problem you may have one of two things, one of the spark plugs or spark plug wires is bad or you have a flat spot on the throttle positioning sensor in which case have be replaced. Good luck?

It should be around 2000 RPMs. Sounds like it's not going into overdrive. Probally an enternal problem.

I had the exact same problem on my 04 GC. I put some Techron Concentrate Plus Fuel System Cleaner in from Wal-Mart and it seemed to fix the problems right away. Let me know.

If the car is not getting into passing gear at all, check the kickdown cable from the throttle body to the transmission, to see if it's broken or binding. Also check the throttle body itself for smooth operation.

If those are okay, then check the throttle position sensor for proper output voltage. That should have thrown error code 24 if it failed.

As you pointed out, your engine has a rev limiter to prevent engine overspeed. As you approach redline rpm's, it will cut the fuel supply. If this is happening at lower rpm's than it should, then the limiter itself could be in trouble.

I hope this helps.

THERE IS A TEMPERATURE SENSOR ON MOTOR WHICH CAUSES THIS PROBLEM... USUALLY IT SHOWS A NEGATIVE TEMP READING WHICH CONFUSES THE COMPUTER CAUSING IT TO REV UP....HAVE THE ENGINE DIAGNOSED ON A SCANNER....GOOD LUCK...

bad mass air flow meter replace it also check for a ecm update at the dealership goes by vin pretty common problem
