2003 Rav 4 periodically stalls at low idle, intersections

Start with the throttle body. I use brake clean and a toothbrush. Clean the plate and were it sits. Wouldn't hurt to spray down the MAF sensor, if it has one. Once you do it, it will take a few seconds to start. Once started, rev it up and spray inside the throttle. Keep it running. Most times this is a $4 fix.

Vortec 4wd 2dr auto trans stalls while drive

you might want to look at your O2 sensors, they can cause the motor to run lean or rich. also you might have an electrical issue that is tripping your ECM. your electronic control module might be faulty. best solution is to get a trouble code reader and find out what your on board computer has stored. from there you can repair and clear the codes.

Could be a fuel issue, Start by changing the fuel filter, if that doesnt work you might want to drop the gas tank and check the strainer on the fuel pump and make sure the tank is clean.

When you changed the egr valve did you clean out the carbon build up inside the intake? if not that could be the problem, if you did, than a peace of the carbon got stuck in the valve, either way your local auto parts store sells a screaned gasget for the egr valve to prevent peaces of carbon from the intake geating into the egr valve, same exact thing happend to me on my 95 blazer.

Have you done any testing? Engine cranking, you have spark at the plugs and fuel injector pulse? Use a gage and check proper fuel pressure, key on engine off, 60--66 psi. The spider fuel system is noted for problems.
Any applicable trouble codes?

Toni Burns Apr 30, 2017

Recently cleared codes, so none coming up. Truck ran fine after changing out TPS (old one broken) . Has fuel pressure, spark,

At the moment, my thought would be to check fuel pressure specs.
How long since overall tune-up? I want to check fuel trims.
