To set the idle speed on a 1996 Mazda Protege, first ensure the engine is at normal operating temperature. Locate the idle air control (IAC) valve, which is typically on the throttle body, and check for any vacuum leaks or issues. If adjustments are necessary, you may need to use a scan tool to reset the IAC learning procedure, as the idle speed is electronically controlled. Always refer to the vehicle's service manual for specific procedures and specifications.
Try the idle air control motor
The idle air control valve is also known as the idle speed valve. On a 1999 1.6 literÊMazda Protege, it is located at next to the throttle body.Ê
9 times out of 10 is a your EGR valve stuck open due to rust, do a google search for protege low idle you'll find it! good luck
"Noisy" because the engine is vibrating more than normal? Low idle will cause the engine to shake. Low idle can be caused by - Dirty/clogged/sticking EGR valve - Vacuum leak or air intake leak - Dirty MAF sensor
Higher then expected Idle, at least 200 RPM. May be a vacuum leak, a dirty Idle Air Control valve.
The correct idle speed is 1RPM x4.2-7.888
It happened to me last week. Turned out to be the EGR valve that was not moving anymore. This valve is used when the motor is in idle which is why the motor was running almost fine when I was putting gas...
I have a Mazda 2001 Tribute and I just replaced the Idle Air Control Valve (IAC). I searched for Idle Speed Control actuator and there does not appear to be one. The IAC is the silver module right on top of the manifold.
it is a camshaft position sensor check vaccume lines also as for some reason this will throw this cone because of rough idle
May be idle position sensor.
on top of the upper intake there is a screw. it can be used to adjust idle speed.
Idle speed is not adjustable. The computer controls the speed with the idle air control motor on the back of the throttle body.
