Taurus 24V DOCH: High idle, 1500rpm, on start, comes down to

Customer Question

High idle, 1500rpm, on start, comes down to normal after about 30 sec. High idle also when driving, seems to push the car down the road without any throtle.

Hi. The throttle position sensor can cause that concern as well. If you have a scan tool you can monitor its voltage to perform a quick check.

Ford tech said that TPS is functioning as it should.

THen you will want to check the throttle linkage. Make sure it is returning to normal. You will also want to make sure there is no obstruction near the accelerator pedal from the floor mat. And you may also want to check fuel pressure and check the evap system vapor management valve. To make sure fuel tank vapors are not getting sucked into the engine when they shouldnt be.

It turns out to be none of the above that you mention. The PCV valve was faulty. Apparently, this is a common problem on the DOHC 24V engines.

Ok. I would not say it is common. Although I have seen this 2 other times at the dealer in almost 20 years. Good find though. Do you have any other questions on this car while we are chatting?

No, thank you.
