We have a 2005 Legacy Sedan that has an intermittent rough idle and/or stalls when braking. It's hard to get started again, but eventually it does. Could this be crank or idler sensor?

SOURCE: rough idle stalls at low rpm's

hello first check your idle with the car running foot on brake see were your rpm reading is if your below 500rpm check your label underhood for your curb idle setting second see if theres a adjustment screw you can increase were your gas cable lever rest against your set screw underhood if you feel confident enough remove your iac motor idle air control valve if the bore were the end of the pintle extracts out to close has varnish builup our carbon it will stick creating vacuum leak type senario causing stalling rough idle sometimes even no start conditions good luck

SOURCE: 87 Supra idles rough and dies out

I would suspect a vacuum leak. At idle under high vacuum the air fuel mix is being leaned out until you have misfiring so bad the engine quits. The exhaust smells rich because even a lean mixture, if it doesn't light off, if full of unburned fuel. At road speeds, the vacuum is low so the engine doesn't care if there is a small leak somewhere. It is getting most of its air through the open throttle. Check all your vacuum lines but remember that even if every line is okay, it could still be leaking from an old cracked intake manifold gasket.

SOURCE: 1999 Subaru Legacy Sedan.. speedometer works

I finally fixed mine, on my 1999 Subaru legacy 30th anniv edition. . .

I removed the speedometer head, and resoldered the green connector on the board. Then I also ran a wire to duplicate the trace wire from the middle pin to the first connect (about 4mm). Problem gone.

2005 Subaru Legacy 198K miles intermittent stalling starts to idle rough. Putting it in neutral and giving gas will keep it from stalling. The check engine doesn't come on and there aren't any faults.

something that wont throw a fault code
i am thinking coil and plugs
even fuel pump relay or bad fuel

Rough idle problem

could be a vacuum leak at a hose or gasket. with the engine running spray a little carb spray at the intake manifold area. if the idle picks up you are close to the vacuum leak. dont spray on the exhaust manifold area, be careful

get the car scanned to find the code. many autoparts stores will scan the car for you or you can buy the bluetooth tool that connects to a phone or tablet that has bluetooth. i suspect your spark plugs might be the issue.

My 1996 Buick Roadmaster LTD engine intermittently stalls.

U DON'T HAVE A CARBURETOR SO FORGET THAT, THE FUEL REGULATOR WOULD NOT CAUSE THIS PROBLEM. I AM A GM FACTORY TECH AND KNOW THIS WITH CERTAINTY. U COULD HAVE SLUDGE IN THE IDLE SPEED CONTROL AIRBYPASS VALVE.
