Unlikely. A faulty IAC will give you poor, erratic idle speed.
my 2002 volvo s-40 is miss firing and it is alleged that the fault is from the idle air control valve. how can i clean the valve?
Wat controls the idle on that type of car its a sensor called a idle control termo valve witch its controlled by the antifreeze temperature and air. it has two small hoses under the throwel you wont miss it . And if u not sure go to auto zone and ask for the idle control valve its a black sensors in and out inlet and out let
under the throttle body. Has a green sensor attached to it. Can't miss it.
it maybe out of timing or the valve seat is leacking use a compression tester to find out if is the valve leak
It may be a EGR valve issue. This valve is normally closed at idle and opens at about 40mph.
More than likely the Idle Air Control (IAC) is defective.
It's the pcv valve (pressure control valve), and it's located on top of the engine block to the right hand side, can't miss it.
Generally if the spark control module on an engine is bad, the car will run roughly. It will likely miss and die at low idle speeds.
timing off, bad plug or wire. Stuck valve
a stuck valve or bad plug or plug wire, or bad cap and rotor to include a cracked or missing vacum hose will make any engine miss.
Birth control pills can make you miss your period, but I do not think you can loose your baby.
you may need a new speed idle control value or your engine has a problem. you may need a new speed idle control value or your engine has a problem.
