Hi All,
My RA Rodeo V6 petrol (2003 model with the Isuzu motor) has taken to snuffing occasionally when idling. It will idle really rough then stop. Usually not when it's cold, but not after a long drive either.

I've replaced the plugs but the problem persists.

Would anybody have any clues?

Thanks,

Greg..

Rough guess would be a really stuffed intake manifold gasket ??? They cause a really rough idle but not sure if it would be enough to stall it ?? .........

Could be many things. Air leak in to intake somewhere as suggested, stepper motor problems, coil packs, leads. You really need to do a bit more diagnostic work and provide a bit more info.

My money would be on dirty throttle body, resulting in poor idle air control. You may be able to remove and clean it with a can of carby cleaner.

Hi Greg, I did a Google search and found a few possible answers to your problem...

1st off, Gas vapor canister plugged, (replace )
2nd, Fuel pressure regulator out of adjust/failing ( replace )

Dirty Exhaust Gas Recirculation (EGR) valve

Cheers, John

Possible EGR not closing and exhaust gas is being fed in when it shouldn't be.

Best to check EGR stuck open or stepper motor control faulty or wiring to it broken.

Have you checked the ECU for logged fault codes?
