You just bought a 86 300zx non turbo and gave it a basic tune up and now it sounds and feels like its sputtering and not wanting to idle you know its not missing it stops at about 2500rpms whats wrong?
It the air bypass unit. be sure there is no leak and the electric connector is attached. To test I have taken it off and temporarily installed a rubber hose. What happens is when you start car the air bypass is open and increases engine idle. Inside the air bypass is a heater that shuts off the air bypass once the engine is up to temp. The air bypass is on right side of engine. It is bolted to engine with two bolts. Air passes out engine through the air bypass and out a big hose connected to air bypass.
How do you adjust the idle speed on a Chrysler Cirrus?
Idle speed on a 1995 Chrysler Cirrus is controlled by the PCM. The PCM operates the idle air control motor. The PCM adjusts engine speed through the idle air control motor to compensate for engine load, coolant temperature or barometeric pressure changes. The Idle Air Control (IAC) motor is mounted on the throttle body and has an air bypass passage that provides air for the engine during closed throttle idle. The idle air control motor pintle protudes into the air bypass passage and regulates air flow trough it. The PCM adjusts engine idle speed by moving the IAC motor pintle in and out of the bypass passage. The adjustments are based on inputs the PCM receives. The inputs are from the throttle position sensor, crankshaft position sensor, coolant temperature sensor, MAP sensor, vehicle speed sensor and various switch operations. Hope that helps.
How do you clean the idle air control valve on a 99 Acura 3.0cl?
IDLE AIR CONTROL VALVE (IAC)Definition: An electrically-operated valve which allows air to bypass the throttle plate in a fuel injected engine to regulate engine idle speed.Buy it new; it doesn't even pay to clean it. It works half the times. But it will go bad eventually…
You have replaced the map and air flow sensors in your 1990 tbird v6 when the air flow sensor is disconnected the engine runs better but the idle is low what could be causing the engine run rough.?
With the sensor plugged in does the engine have problems while driving at normal operating speeds? Is the problem just at idle. Your IAC (idle air control) may be bad. Go to autozone.com to pull up a picture and location of it on your vehicle. You can also unplug this to see if your idle levels out.
What is the position of the idle air control valve during idling?
it is open at idle to allow air to bypass the throttle body into the intake manifold
Why does your car vibrate and cut off when you idle?
Problem is related to idle solenoid. As you come to a stop the throttle closes. There has to be a bypass to allow air to flow into the engine. This is acheived via an idle solenoid valve located somewhere to the intake manifold and it is controlled by the computer.
What is a idle air bypass valve for a 1991 VW Golf GTI 8 v?
On VWs, the Idle Air Bypass Valve is generally referred to as the Idle Stabilizer Valve (ISV). The ISV is designed to maintain a steady idle speed. It is mounted on top of the cam cover on mk2/A2 8v Golfs.
Where is the Bypass Module on a 1995 ford explorer?
I'm taking a guess here , that you are asking about the air bypass valve , also known as the idle air control valve. It is located on the driver's side of the engine , mounted on the side of the upper "plastic" intake manifold on the 4.0 L overhead valve engine not too far from the throttle body. (Helpfull)
What does a idle air control valve do?
IDLE AIR CONTROL VALVE (IAC) Definition: An electrically-operated valve which allows air to bypass the throttle plate in a fuel injected engine to regulate engine idle speed. IDLE AIR CONTROL VALVE (IAC) The (IAC) is located under the Triton Plastic cover in the middle of the engine compartment. Very easy to replace. There are two bolts and one plug.It should only take you around 10 or 15 minutes to change. Buy it new; it doesn't even pay to clean it. It works half the times. But it will go bad eventually…

What if your engine doesnt go below 3000 RPM?
If it's a ford, I'd check the Idle Air Control Valve (IAC) High engine idle can be caused by alot of things though such as; ECU (computer) malfuction, a leaking intake manifold gasket, or even as simple as a disconnected or leaking vacuum hose.
What causes a 1981 Chevy 305 to idle very fast and actually push the brakes when you stop?
Check the Idle Air control valve. This lets air bypass the throttle body plate when the car is at idle or low revs.
