Where is Idle control valve located and how do you know if it's bad? My 1994 Toyota pick is idleing ruff and skips a little while running down the road. I've changed the plugs and wires also had the head...


Idle air control valve only controls air into the engine while idling. If your vehicle is running rough and skips, its misfiring. Make sure that the new plugs are properly gapped and timing is set right on the distributor side, intake hose isnt leaking. Re-inspect the sparkplugs for fouling (black, burnt, brown etc). if ok, have the computer scanned for the error at autozone (free). Post the code online...hopefully this helpd

89 Honda Prelude failing emissions rich


is everything stock? and you have catalitic converter in place?

Stop by Schucks auto supply and have them run the codes. i'm sure there is a code if you cant pass emissions. your check engine light bulb is probably out.

and usually the first cause is the first o2 sensor.

You need to Replace your Gas Cap. The Seal is worn and it is allowing Air to get inside the Fuel tank Causing your Rough Idle.
