ford service rant

[wadsymoo]

hey guys,i had a experience today with byrne ford service,been having a few issues with my AU2 xr8,the car is cutting out and felling like its running out of fuel, so i thought id get ford too look at the car as ive had no joy with a few other mechanics.

anyhow they said it took 3.7n hrs labour at a cost of $396.00 too put a scan tool on the car and diagnose it was the o2 sensors that needed replacing?problem is the car still not fixed and im feeling rather ripped off as i think its rather expensive.do i have any avenue too take with them over this?
just looking for opinions i guess,cheers jas
