Your idle speed is controled by the computer on this car. so yo could have a variaty of things going on here. but i am willing to bet you have a leak some were on the intake to see if it is your intake gaskets wich is common on newer cars you can buy a can of brake cleaner and start the car and spray it on the out side of the intake. but be carefull not to get any electronics or the throttel cabel with the cleaner. if your intake gasket is leaking you will hear a drop in the engine Rpm.

94 Isuzu rodeo started to idle high


Vehicles tend to idle higher for two main reasons, as the temperature becomes colder, the engine must work harder to warm itself up so it idles higher to accomplish this faster. The second may be due to a vacuum leak in the engine. Any other symptoms?

My 1994 ford probe will not idle at all do you know what could be causing this


A defective idle speed control valve or one that is clogged with blow back sludge, try cleaning as th enew one is about $300.00

To correct this problem Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional.

Most likely is your idle speed timing, there is either an adjusting screw, or you need the dealership to place a diagnostic tool on there threw the computer to set it down some.
