SOURCE: car will not start when

hi there, when air flow unplugged, ecu goes into limp home mode ,a back up if something dies whilst driving. it sounds as if your used mass air flow sensor is faulty , they are more fragile than they look, one knock and these early fine wire models are gone. i replaced many when i worked at a volvo dealership a few years ago. hope this helps, and good luck.

SOURCE: I have a 1999 oldsmobile

fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck

SOURCE: 1997 buick lasabre custom high idle, transmission, stalling

had same problem i would check the Idel Air Valve and also check all of your vaccum hose lines makeing sure there are no cracks or splits in rubber connectors if there is repair immediatelt because over time they start to dammage the internal parts fo the engine and if youve replace tps mass air etc. sounds like a vaccum hose problem

Hi Aaron. With all due respect you need to stop changing parts and find out what the check engine code is. You're just guessing at what's wrong.

Get the codes read, they will point you in the right direction. There are too many things to list here all the potential causes without those codes. It could be the idle air controller, fuel pressure, clogged catalytic converter, etc., it could be a lot of things!

Most auto parts stores will read the codes for free, or you could pick up a basic code reader for as little as $50 - $60. Once you have the codes, post back here or look them up at http://www.check-engine-light.com

SOURCE: mass air flow sensor bad on 2002 monte carlo ss

It's should be a simple remove and replace. Just make sure the engine is off. Also do not touch any of the filament wires on the sensor, just the plastic housing. Also after you install it drive the car for a little while (city speeds, cruising speeds and inbetween). That way the computer will be able to readjust its setting since it is a new sensor.

2000 kia sportage 4x4 never seen anything like it. changed plugs both coils and both plug wires all bad and still starting rough press on idle feels like not getting enough gas high idle sensor off.


-Not always the plugs and the coil case this. This can be cause by bad injector. Dirty mass air flow sensor.
-First Clean mass air flow sensor. If it's still do the same thing
then check the resistance of every injector. If it's not within its specification then replace it.

Good Luck

My 2000 Ford Expedition 5.4L V8 4x4 idles really bad when stopped at a red light. Sometimes it will just stall. It always starts back up. It goes just fine when I hit the gas, real smooth and powerful. It...


Check the idle fuel pressure. Load the electrical with headlights and heater defrost etc and see if problem gets worse. Attempt again with all accessories off. Could be fuel pump is getting low voltage at idle or fuel pump is failing. Bad fuel pump would definitely be a problem high fuel demand. Check vacuum line between pressure regulator to intake manifold.

Check for a air leak in the intake manifold. Gasket/hose etc. The P0171/P0174 is an indication that not enough fuel or tow much air. You can sometimes hear the air leak during idle.


Best solution is to use a graphic capable scan tool and watch the fueling trim/idle.

1996 t bird 4.6l idles up and down


If it idles up and down real high, its the throttle body sensor. If it's a low up and down idle and runs rough it is mass air flow meter. If you unplug the mass airflow meter and it will just low idle (no up & down) then the mass air flow meter is bad.

My car is idling too fast, where is the idle cable,so i can alter its idle speed , i have a 1995 bmw 316i se


it's not old carbureted chevy, it's not idling high because there's too much tension on the gas pedal cable.

look at replacing/cleaning: idle control valve, maf(mass air flow sensor) vacuum leaks: intake manifold or air intake system.

I have a 1990 Chevy 1500 SS truck with a 454ci. that has an idle


You don't have to try both, but...If you can get a scanner hooked up, you can see the TPS move as you depress the throttle, and verify if it is good or bad. The IAC can also be viewed with a scanner, and they get gummed up, and most can be cleaned.
Also, a bad temperature sensor can cause a high idle if it thinks it's real cold out.
Also, a bad power steering pressure switch can cause a high idle.
All of these can be looked at with a scanner!

Welcome to fixya, check the idle air control and the mass air flow sensor.

I have replaced the throttle position sensor, egr valve, o2 sensors, mass air flow sensor, fuel system, and my 99 trooper idles high, and shuts off


Check the Idle accelerator valve located on front side of throttle body, it is either stuck or needs cleaning real bad, this is what controls your idle speed, by letting small amount of air in. It has a plunger on it that moves back and forth slowly to adjust amount of air mixture, it is controlled by computer. Unplug it and just turn on key and check for voltage.This valve gets real gummed up, probably need to take apart throttle body and clean. HUNT

Idle air control at base of throttle body. Passages could be plugged or idle hard stop needs adjusting.

Air Intake System Sensors Air intake system sensors include a heated resistor-type mass air flow (MAF) sensor and throttle position (TP) sensor; both supply data to the powertrain control module (PCM). The PCM also monitors engine speed.
Air Intake System Control Devices The idle air control (IAC) solenoid regulates idle speed by adjusting the amount of air allowed into the intake manifold. Adjustment is made by varying the duty cycle output by the powertrain control module (PCM). The PCM will increase the duty cycle for added mechanical or electrical loads. The IAC solenoid is combined with the fast idle control (FIC) solenoid which is turned on when the air conditioner is engaged to help compensate for the additional load. The IAC valve must be replaced as an assembly with the FIC solenoid.
Fast Idle Control (FIC) Solenoid The fast idle control (FIC) solenoid (Figure 1) compensates for idle speed change caused by the operation of the air conditioner compressor. The FIC solenoid is controlled by the FIC relay. The FIC relay is energized when the air conditioner clutch is energized and the relay allows the FIC solenoid to turn on and let an additional volume of air into the intake manifold.

Throttle Body (TB) The throttle body (TB) controls the amount of air that flows into the engine through a single butterfly valve. The single butterfly valve opening is determined by the accelerator pedal. The TB is cast with an air bypass channel and houses several emission-related components for the powertrain control module (PCM).
--------------------------------------------------------
Throttle Position Sensor (TP Sensor) The throttle position (TP) sensor responds to the accelerator pedal movement. The TP sensor is a potentiometer that transforms the throttle plate opening angle into output voltage and sends the voltage signal to the powertrain control module (PCM). In addition, the sensor detects the opening and closing speed of the throttle plate and sends the voltage signal to the PCM. Also, the TP sensor is used to determine the air intake when the mass air flow (MAF) sensor fails. This mode of operation is called Fail Safe.
The TP sensor integrates the idle (IDL) switch within the housing. The IDL switch detects when the throttle plate is closed and an idle condition occurs. The PCM is supplied with this input signal.

1992 F-150 Idle is to fast


check you throttle positioning sensor, also check your mass air flow sensor, by unplugging while your motor is running if idle returns to normal that may be the prob. hope i could help

I had the same problem. I changed out the idle air control valve and that solved the problem. Somehow the electrical connector fried out some of the pins.
