Hi guys,
I have a 2004 BA XR6 turbo that's had high fuel consumption and rough idle for months now.
I have changed the oxygen sensor, Throttle position sensor and most of the rubber seals on the air intake manifold/ throttle body and turbo. I've also given the throttle body a good clean and reset the ECU/TPS. The car doesn't feel like its gonna stall any more but the idle is still a bit rough. The needle doesn't sit still and fluctuates up and down over about 100/200rpm. The fuel consumption hasn't changed at all. I know the manifold isnt leaking. There has been no noticeable loss of power.
Here are the symtoms:
- fuel consumption has jumped from 13lt/100km to 17.8lt/100km
- idle was pretty rough. Sometimes stalling at the lights
- while accelerating under load when the car still fully hasn't heated up it feels like the fuel cut off comes on, the car loses power and wont accelerate further until I remove my foot from the accelerator.
Any help/suggestions would be much appreciated.
