hey all i just fitted a full exhaust system to my 6lt and now im getting a power train fualt code on the dash, i get the feeling its got soming to do with the oxygem sensors ,has any one eles every come across this problen befor and how did you fix it??
Yeh put the scanner the codes are P0420 bank 1
P0430 bank 2
P0420 pd bank 1
P0420 pd bank 2
Catalytic converter system- efficiency blew threshold
I pull out the oxygen sensors cleaned them up, start the car n it's pushing out black smoke, the codes haven't come back thou I haven't had a chance to drive it
Any performance shops who has the software should be able to do this for a small fee. Make sure they dont turn it off completely though, just the emission related codes.
I feel your pain bro I had the same problem but every time I got the code wiped within an hour it was back in the end I got the car maffless tuned and got an otr fitted and been perfect ever since. But that was an expensive way to fix it
i bought a scan tool off fleabay for 300 bux that you can use to read and clear codes - I'd get one
