Question about 1996 Toyota Camry

Open Question

The car starts fine but wont idle. INSTANTLY cuts off as soon as you let your foot off the accelerator.

When I bypass the pcv valve its back to perfectly normal. It starts without having your foot on the pedal and stays idling just fine. But cleaning the pcv didnt fix it, buying a brand new pcv valve didnt fix it. But again, when I take the vacuum hose off of the pcv it starts and idles perfect. I unhooked a few sensors and tried each time but it still starts fine as long as your foot is on the gas pedal but as soon as foot is off that pedal, INSTANTLY it shuts off like you turned the key off.

SOURCE: engine wont idle unless you keep your foot on the gas pedal

First, try a new accelerator pump. They're less than $10 and easy to install. On the side of the carburator, near the linkage. It's simple a small rubber diaphragm.

SOURCE: 94 camry. 2.2 fed emissions.

Before we both knock ourselves out with fuel injector testing. Hook up a Digital voltmeter (DVM) to upstream O2 sensor and lets see how she is burning. Remember positive lead of DVM to signal wire and negative lead to ground. Anything above 550 mV is rich anything below 350mV is lean. Be mindful that an exhaust leak the size of a pin hole in this region can cause a rough idle. A healthy reading should bounce between 550mV and 350 mV.
Next to test is O2 is working block off air in take making mixture rich and see what O2 says about it . Then pull off a vacuum hose (a lean condition) and see if DVM drops to 200to 300mV's.
Keep me posted.

Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.

Please Help!!! Replaced ECM and truck immediately dies


Have checked the idle air control valve. If stuck closed it will not allow air to bypass the throttle therefore it will start and stall.

2003 toyota highlander will not idle, must keep foot on the accelerator to keep engine running. AS soon as my foot is removed from the accelerator the engine cuts off.


The first place I would look is the IAC motor (idle air control) usaully on throttle body and possibly dirty throttle body and one last thing could possibley be EGR valve exaust gas recir. as if it stuck open it will lean out engine.

In park the engine dies; only will run if given gas


It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.

I have a 91 cutlass cierra and sometimes it idles fast and then cuts out on me, even tries to cut out while going down the highway. Sometimes I have to have my foot on the brake and accelerator so it...


Have a look for broken vacumn lines ..this causes air to bypass the idle air control solenoid/motor..and this will also cause the exact symptoms you are concerned about..also the pcv valve stuck open will do this as well..start the car if it will stay running long enough and look under the hood and listen for the vacumn leak some times you can hear it and you can locate it this way as well..good luck

(1)Car overheating (2)Car starting and cutting out


1- There are 2 fan systems in your car. One is a fan clutch. the other is electric fan. The electric fan is still working, but the fan clutch is not. Replace the fan clutch will take care of this problem. 2- When you put flat down on accelerator the car starts since at this position the throttle body open all the way making a correct air: fuel ratio of 14.6 :1. When you release the accelerator,the throttle body has to go back to it preset position and at this position it didn't make a correct air: fuel ratio of 14.6 causing the engine die instantly. This means your throttle body needs cleaned. There is a vacuum thermal valve at the top engine block to answer your question. It can be easily identified by looking at 2 vacuum hoses from this valve running down to the throttle body.
