Default 02 Montero LTD EGR

im at a complete loss.


I threw codes for Injectore Fuel Pressure Regulator valve and EGR. Replaced both.

Threw a code the that insufficient EGR flow/ bank 2 running lean. Recommend that I get an EGR solenoid. Just replaced that today.

( rough idle too. But not showing on the tack)

Still throwing the same codes. Can someone please enlighten me as to what I do now? Or what might be the issue??

EGR flow malfunction may also be due to a problem with EGR valve itself, or obstruction in the EGR pipe. If your EGR valve is vacuum modulated - plug a vacuum pump into it and with engine at idle apply vacuum. The engine should stumble and die. If it does not do this - you have a problem with the valve itself or with the piping. Unbolt ERG pipe from the engine (driver side) and see if there is any crud obstructing things. Take out EGR valve from the manifold and make sure the hole in the manifold is clear. If the vacuum test works properly - check the vacuum hoses. You may have a cracked/disconnected hose that prevents actuation of the EGR valve. Having a cracked vacuum hose will throw the same EGR code as a bad solenoid or bad valve.
