The likely causes would be 1) plugged EGR valve: The valve gets plugged with carbon deposits over time and needs to be cleaned out. 2) a cracked air intake hose: The cracked hose causes air leakage which throws off the Mass Airflow Sensor, which when sending erroneous information to the computer can cause serious hesitation and stalling at idle.
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
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...
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
Try the idle air control motor
Higher then expected Idle, at least 200 RPM. May be a vacuum leak, a dirty Idle Air Control valve.
it is a camshaft position sensor check vaccume lines also as for some reason this will throw this cone because of rough idle
I had the same prob, turns out it was a vac hose that needed to be replaced not the fuel pump
ford focus stalling at idle but not cutting off the check engine light is on please help so i dont get rip off thanks
if you find a answer on the idle issue let me know my 95 does the same thing as far as smoking mine does that too when its cold out i was told it was the valve seals r bad
Why is that my idle is low what cost that to do it
"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
idle control valve is shot!!
