Hi all,
I have an fg xr6 turbo ute which I bought new in 2008. Ive fitted a v2 rapid cooler xforce 3.5" turbo back system and deka 60 pound injectors. The car was tuned locally here in cairns and has since had many dramas with engine fault codes. All 02 sensor related. Ive had the car back at least a dozen times to get the issues sorted but with no luck and im pretty much over it. The car runs rough at idle, seams to run rich ( black smoke) poor fuel economy and nearly stalls when pulling up at traffic lights when these codes are up. My tuner apparently has sent the tune to nizpro which have confirmed there iz nothing wrong with the tune. Lol apparently they told him to pull the bulb out of the dash. It seems he has anyhow because the faults are still logged on the ecm but no lights are displayed. Hes changed out the 02 sensor also. But the problem still arises. Other codes have been 02 slow response codes. Any info would be much appreciated. I may even drive to townsville to hopefully get the problem sorted by another tuner, if that is thought to be the problem. Sorry for the long winded post and cheers for any help.
