powertrain problems PLEASE HELP

[jda thunder]

gday everyone, please i need help..
i own a my06 ss thunder 44000kms, i bought at 33000kms, within that time the powertrain light has come on 4 times.. 2 02sensors have been replaced, the 3rd time they told me my cats where ratshit and needed to be replaced, i have an aftermarket exhaust with holden cats, took it to a muffler specialsit he told me my cats where perfect, took it back to holden they didnt know what to do so he reset the computer, the light came on again today so i rang them and they told me there is nothing they can do they are out of ideas. anybody got any ideas before i drive my ute into the ocean!!!!

umm go to a competant holden dealer, if they cant fix a problem when the computer that is giving an indication, they have problems

another thought came to my head, i remember a couple of people on here having the same problem, i think it might have been caused by oxy sensor not being positioned right, im assuming you have the vz with 4 oxy sensors? can you check to see if the oxy sensors have been moved or is the new exhaust fitted from the flanges roughly in the middle of the car?

i took it back today, no luck. said they cant diagnose the problems under warranty and if they replace the sensors it wil keep happening. they gave me this number for a bloke that can hack into the computer and turn the sensors off???? any thoughts??

dont do that. there are 4 o2 sensors and they would of replaced the easy ones you need to find what bank and number it is thats playing up. also check if they plugged it in correctly they do have problems with o2 wire contacting the heat shields, and is the software up to date? they sound like drop kicks to me. if it happened b4 twice they should of looked deeper into the problem like the wiring
