3.0L:auto. trans- oil gauge flickers wildly at stop when engine is at operating temp. (have to apply brake and run idle higher with gas pedal)...what is wrong?
The vac modulator only assists the transmission in knowing when to shift up.
If the engine oil pressure gauge is acting wildly, it could be the sensor or the oil pressure could really be going up and down.

Sounds like youi may have a few serious problems going on to have that kind of back lash occuring at higher speeds. I have experiance with low spped clunks on Bronkos and your type of vech being a car dealer. One you might try for low speed clunk on take off and braking at stop likts just completeing a stop? Pull the drive shaft and lubricate the splin - two check your leaf springs for weakness and wore bushings - take a look at your shocks - three u bolts holding springs to rear axle housing may be letting the axle housing actually dip or tweak or all those thing in combination - now you may have some serious slop in the pig - transfer case may be causing that clunk - as far as high spped clunk and activity you have a serous problem and you just might drop the transferr case have an accident fliping over..............Mike South Bend Indiana don't just keep driving and making problem worst...........
SOURCE: when push gas pedal, oil pressure goes up
have you oil pressure sending unit checke/replaced
SOURCE: 2000 Taurus. Will not idle. No check engine light.
check on the rear of the engine below the throttlebody area there is a vacuum line that collapses or splits and cause this
SOURCE: engine revs remain high or increase when braking
Have you tried checking your throttle positioning sensor. Possible vacuum leak or check for carbon build up in the throttle body not letting the throttle valve shut all the way.
