    no engine light on

  • Christopher Foulkes May 11, 2010

    A surging idle is usually the result of a vacuum leak or possibly a bad mass air flow sensor. The computer may be adjusting accordingly which is why it smooths out shortly after starting. Is the check engine light on?

Sounds like a bad Idle Air Motor or a vacuum leak somewhere in the manifold area. Can make the car search for an idle....

My 96 ford taurus revs high when starting then works it way from 1500 or more down to 800 but fluctuates from 800 to a little over 1000. When putting car in rverse or drive from park engine revs up to...


You need to clean the IAC again and also the throttle valve and bore, use only CRC brand Throttle body cleaner. After they are thoroughly cleaned disconnect the battery for 5 min's and then drive the car in varying condition for a few days. If that doesn't cure the issue you have more serious problems and will need a scan tool to look into the readings from the MAF, TPS and ECT sensors. High idle cold start is normal then slowly dropping after a few minutes. I assume you never had a check engine light. Correct?

I have a 1998 Ford taurus. It starts fine but then dies and also when slowing down the RPM dropped and it stalls. Can start again, but it dies off pretty qickly.


need to check the idle/air control valve.the valve gets sludged with oily tarnish and moves slowly and can'y keep the car idling properly. may also want to clean the throttle plate , it too can be sludged with the same tarnish limiting the air flow.

Why does my 2000 ford taurus idle so high when i start it


That is just the way the engine warms itself up to operating temp and gets the oil and fluids moving around to lubricate the engine.

I have a high idle problem only when the engien is cold. I replace the IAC which i thought it was going to solve my problem but no luck, it didnt change a thing.


It is normal for engines to idle faster, when they are cold. Once it warms up, it should slow down to somewhere in the 650 - 750 range.

Why does my 2000 ford taurus idle so high when i start it


this is normal, if the idle wasn't high (about 2,500 RPM) the engine wopuld stall out until it warms up to normal temperature. If it is above 3000 RPM for more than a few seconds you have a problem.
