Question about 2000 Ford Taurus

1 Answer

My 2000 Ford Taurus at about 4000 rpm does not go further with rpm even when accelerator is press more. It gives off a pulsating choking sound at above mentioned rpm. At below 4000 rpm the engine runs smooth. It could be a faulty air sensor?

    Hi Chuck943.
    It happens while driving and when in park gear. I did not check in neutral gear as of yet. Engine starts nicely in park gear, drives smooth with no problems, but when needle RPM gauge is about at 4,000 rpm and when I press accelerator further more the rpm gauge needle stays at about 4, 000 rpm and engine chokes in the pulsating manner like puff, puff, puff even when I press accelerator pedal all the way to the floor. Thanks Chuck943.

    Thank you very much Chuck, you are wonderful and fast with replies.

    I did not inform you that I also had a check engine yellow light on my instrument panel was on when driving and at park.Then I decided to disconnect the positive and negative clamps on the battery and after few minutes reconnected them back. The check engine light of the instrument panel disappear (turn off itself). But it might show up again I think. Maybe this behavior might indicate something else.

To do this in park or neutral is normal. To do it while driving is not.
There are so many things that could cause this but if you have no check engine light and it runs normally up until then I would suspect you have an exhaust restriction. This can be checked fairly easy on this vehicle, it has a DPFE sensor that mounts near the top back side of the motor.It will either be black or silver,will have a 3 wire connector to it and 2 hoses going down the back of the motor to the exhaust. You can disconnect one of these hoses and install a vacuum/pressure guage and measure exhaust back pressure. It should be 1 psi or less at idle and when you go to wide open throttle should not exceed 3 to 4 psi. If it does something in exhaust,most likely one of the catalytic convertors is stopped up.

    Yes it would be good to have the codes retrieved to determine what systems are suspect however,the test of exhaust back pressure can be done to verify exhaust restrictions and done very easily on this vehicle.

Rpm does not reach 4000 rpm


Neutral or Drive N rev limiter to prevent engine damage from no load over acceleration. D: many things could be at fault. Has your fuel filter been changed in the last 30,000miles. What about a tune up? Is your CEL(Check Engine Light) on? If so have a parts store check for codes, some do it for free. Then get back to us and we can go from there.

I got a 2002 Taurus n it runs fine upon hard acceleration until 3000 rpm to 4000 above that it's fine again, in between 3 n 4000 it spits n sputters like a misfire! No check engine light comes on.


That sounds like the camshaft synconizer..They dont oil good and they can squeak like a belt,,usually after a few mins of running..When your at wide open throttle the computer ignores the cam sensor so if it gets a bad signal,,it doesnt see it,,and you get no light...Look at the back of the engines intake..where the wires cross over to the firewall side..Under the throttle body..Listen carefully and see if you can hear it squeaking..Sometimes you have to use a hose to listen

Where is the voltage regulator on a 99 mercury cougar?


The voltage regulator is a part of the alternator.If you are having pulsating issues then look for grounding issues like a corrided eyelet or loose grounding bolts.
