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.

sounds like a bad throttle position sensor or a fuel pressure regulator. also check the idle air control vavle

I have a 2004 Jeep Grand Cherokee Laredo 4x4 with the 4.0L. It has approximately 150k miles on it. I started the Jeep with 1/4 tank of fuel in it and it started rough and acted like it was going to die....


long post.
ill reduce it for you.
misfires. (is RPM below 700 then misfire can be normal) for idle speed controls dead.
ISC the isc controls speed, of idle,.
mine stuck like zillion times, in 400k miles. endless.sticking
mine was a tiny gutless stepper motor drive ISC valve.
the cone valve is side gets nasty and sticks (
(PCV gases caused as seen on all engines)
i clean it.
the proof is the easy press of right foot easy raises idle back to 700rpm and engine stops misfiring.
ever get a tuneup this decade or running spark parts 500,0000 miles
for the new world record.?


now the tricky part of ISC, , fully explained in the SM serv. man.
the PCM learns its behaviors.
it learns all hot start settings and cold
so when you key on, it goes to the correct HISTORICAL spot.
if it can move there(sticks) engine car race.
or run too slow,
cold start would be worse, as hot isc is more closed
so if sticks there closed, the next cold start will be horrid
some newer manuals telly you to add 5% throttle if car is hard starting this is so common.

clean it. end story.

92 GMC won't crank without using starting fluid. Once it cranks it runs find until I take my foot off the gas pedal. Then it wants to die.


The device that controls your idle speed is the IAC, idle air control valve. it gets gunked up but can be brought back to life with a can of spray carb cleaner. While you are at it clean your PCV valve and the throttle bore and plate as well. Use the remainder of carb cleaner to check for vacuum leaks at hoses and the intake manifold. just give some short shots around the engine until the idle speed changes; showing a vacuum leak.

90k , timing belt new @ 80k worked fine sprayed engine with water to clean dust started and ran fine nest day started but then idled up to 4k and wouldn't idle down drove it about 5 miles and got off...


I have ran into this problem at my shop. There are 3 things that could be bad. Idle air control valve, pcv valve or the vacum hose for the pcv valve. Vicually inspect the pcv vale hoses. If you dont see a tear, spray carb cleaner around the hose, if engine idle changes there is a vacum leak in hose some where. If pcv valve and hose are ok than its your idle air control valve. You can attempt to remove part and clean it but this is only a temporary fix, Good luck.

After starting my 1999 Dodge Durango, when I take my foot off the gas, the vehicle shuts off. As long as my foot stays on the gas pedal, it stays running.


I had the same problem it was the idle air control valve, I purchased another but problem remained, so clean old one with carb cleaner and steel wool put back on and worked great again.

Car will not start without pressing gas pedal to keep idle speed up. If I keep idle at 900 RPM or higher it runs as long as foot is on gas pedal. It then stalls out when I take foot off gas pedal. No...

2001 Jeep Wrangler, Starts and runs fine, but stalls at idle especially when warmed up. If I remove the vacuum line from the PCV apature, (it does not have a PCV valve, the jeep seems to idel up to normal...


If you cleaned the orfice tube and it got better, it is possible you have lots of gunk in the valve cover that is getting back in there. re-check what you did to see if it's obstructed again.
Your idle is controlled by the control valve usually next to the throttle position sensor on the throttle body. You can remove it and clean out the passages there. Be careful not to turn the pintle valve and don't loose the "o" ring if you remove it. Make sure you keep it straight when putting it back in.(once bent, it's junk)

Wont hold idle will start with foot depressing gas pedal will run with foot on gas but stalls when foot removed


Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.
