Hi all,
My VE Series 2 with 3.0 SIDI has been stalling the last 5 days. Engine runs smoothly then for no reason it can shudder then stall, or cut out completely. When this happens and I leave the ignition on, the butterfly on the intake is clicking on and off rapidly. The dash displays engine immobilised.

When I try to restart, most times it won't start straight away, but if I wait a few minutes it will, but then again will stall within 30 seconds. After cooling down for a few hrs it will run again like normal until this happens again.

Took it to the mechanic who picked up a fault in the battery. Changed that, car ran great for 4 days but is now doing it again.

The only error coming up on the scanner is " key transponder key error". He thought it might be the transponder being faulty and the computer switching on the immobiliser when it couldn't find the key, but then he thought that when the car has been started, the key is then bypassed as it would be unsafe to switch the car off when driving.

Anyone else experience this at all? I'm thinking either the TPS or ECM.

Would Holden have better diagnosis equipment better than a general necessary than a general mechanic? His scanner was about the size of a laptop and had my model car in its database.

Thanks.

Ok. My auto elec has pulled the following code off the ECM.

DTC B3935 (Transponder Key Error).

Funny, as the car starts, and I can't imagine the the ECM would cut the engine out after starting thinking there is no key, that would be dangerous.
He's going to relfash the ECM to see if that clears it, if not he's talking about replacing the modules and maybe the instrument cluster.

I frankly am not keen of replacing items just to see if that fixed the problem. Has anyone else encountered an intermittent stalling problem in the VE Series 2 and also had this code returned?

Thanks.

I think it was just a passing comment.

Anyway, my car is now at Holden. My auto elec says it is a problem with a module in the dash somewhere (he called it the ECM). Says he can't fix the issue as the codes he needs to replace/reprogram will not be released by Holden.
