Hi all
I did a l67 conversion into my 98 model vs ute just over a year ago, one issue I had was I kept getting code 76 so I did the earth mod on the o2 sensors earth from D14 to D16 then to A2 to chassis and I no longer get the code, the thing I don't get is that i never had the issue before with the ecotec engine, yesterday I removed the earth mod wire from D16 took the car for a drive & no code 76 then I disconnected D14 on the earth mod & code 76 appeared, so this got me thinking the only other thing I changed in the conversion was the memcal the original ecotec memcal has the ckul bin on it, I don't know what bin is on the l67 memcal could this be the cause of code 76 thought's thanks.

Re: O2 earth mod
I believe the issue is a poor earth on the engine, I think at the front on the drive belt tensioner.
Whatever it is leave the extra earths in place to be on the safe side
