I have been haveing problems for the last four months where my car won't start every Thursday. The car turns over but won't start and when it's does runs rough and sometimes stalls. It's done it twice after refilling and the other times just when starting it in the morning. Took it to a mech. They could not find anything. And only code that come up was to do with the key coupling code. What ever that is. It has come up check power train once when it would not start for five mins turning the engine over. Again no code
I have replace air and fuel filter. Cleaned MAf sensor. Spark plugs o2 sensors. Checked throttel body. Just wondering where to try next. Fuel pump. Imobilers maybe. ???
Only on thursdays??
I could never quite get the hang of Thursdays...

The car wants u to start ur weekends early!
Seriously,
Key coupling code is to do with you using one key then changing to another. Cause its a rolling code thats always changing, it will throw up an trouble code.
if you've had check powertrain come up id be checking under the car & having a look at ur O2 sensors.
The Blue One
both 02 sensors have been reaplced at the front. Well oxygen sensors that is. is that the same thing?
prob just cause will fill it up most thursdays i think. maybe a heap of shit in the fuel tank
Just found this on Holden handy hints web page will give it ago and see what happens.
