The egr valve may be faulty or leaking air. Otherwise you may have a plugged or cracked vacuum line or low vacuum pressure

SOURCE: How to clean EGR valve passages in 1993 Isuzu Trooper DOHC V6

You have to the EGR valve (sometimes the Intake manifold to EGR Vlalve line also). After you remove it take a drill bit the about 20 % smaller than the actual hole of the outlet side and rotate the drill bit with your hand to dig out the carbon. Aditionally the line coming from the intake manifold to the EGR valve will clog near the connection to the EGR valve. I use either a single piece of copper wire or the wire that you would use to tie ribar together to clean the line. When your done cleaning take a piece of vacuum line and connect it to the diaphram side and **** on it... then plug the line well with your thumb. Grasp the valve and blow thru it... Air should blow thru it freely. Remove your thumb from the vacuum line and try blowing again.. No air should pass thru the valve.
Then reinstall the valve and start the vehicle with the vacuum line disconnected (but blocked off) Use another piece of vacuum line connected to the diaphram again and **** on the line.. The vehicle should die or run really bad. If it does this then you cleaned it correctly.

For a V6 # Liter engine, you will use a galon and almost half (that is about 6 Liters of oil). I use a Toyota camry V6 3 Liter engine that shares the same engine with the Toyota 4Runner.

2000 Toyota 4Runner stalls on idle


On Toyota 3.4 liter V6,there is small vacuum switch call vacuum switching valve (VSV) that may be disconnected air tubes,electrical connector or malfunction.

I will spend one hour to look over the engine from top to bottom to check for bad connections and disconnected vacuum / air tubes.


Are you getting any additional OBD-II code(s)?


Please post it on the comment window.

Wiring diagram for 1993 toyota camery v6


Does the engine run properly when you drive it? Does it accelerate normally, or does it hesitate & ****? If it runs poor, it may be the wires crossed. If it just stalls at idle, you may have a bad Idle Air Control (IAC) valve, or a partially stuck open EGR valve.
