Re: 01 Highlander Stalling
Is this a i4 or v6? Does it stall at idle/low rpms when braking or moving from a stop. Hopefully not when you're moving.
I've experienced a similar issue with older higher mileage i4 toyota's (camry's) stalling at idle or low rpms. It was due to a dirty or nearly clogged idle control valve. I don't know where it is exactly on the highlander, but it should be near the throttle body at the bottom of the opening. Remove the lines going to it and spray it down with like carburetor cleaner. Scrap the opening if you have a brush that is small enough. Not into the TB, but the valve openings.... You will see it.
That's just one cause, which I've seen on some toyota's, but there could be some others.
If these symptoms, don't apply to you, post exactly how and when it stalls.
