V6 running rough, cold, lacks power

[fxtrader]

Hi everyone,
My VT V6 commodore runs really rough at idle, lacks power, runs cold, and uses excessive fuel. I've changed the plugs and leads, it doesn't have a fault code flashing, I'm wondering if anyone knows what it could be?
Thanks.

It could be any number of things but try checking the rubber hose that is connected to the bottom of the throttle body. they tend to become loose and disconnect.

Oxygen sensors? Runnin on moonshine?

The temperature gauge does not get past 1/4 warm. Normally it runs exactly in the middle of the temp gauge.

Maybe your thermostat is stuck open?

Running on 5 cylinders?

Maybe take it to someone who knows what they're looking for & might be able to diagnose the issue.
