Low Voltage O2 Sensors

[Dan]

I did afew upgrades all at once LS6 intake, BBK 80mm p/p throttle body, Granatelli MAF and a used optima battery.

After I finished installing everything I took the car to get a Frost Tune because I deleted my egr and wanted to get rid of my check engine light.

After the tune was done the light went away but after driving it for afew minutes it came back on. I now have codes saying that I have Low Voltage from ALL my O2 sensors.

Anyone have a clue why this all of a sudden came up? I never had this code before all the upgrades.

BTW thanks for the tune Frost car shifts and run a ALOT better overall.

I'd get ahold of Frost and talk about those O2 issues. The rears shouldn't be a concern cause they should be tuned out.

Im sure the O2 issue was because of the mods done not the tune Frost gave me.

Im going to try going back to my old battery since I never had an issue with it before.

I will have to say though the $125 tune from Frost was the best mod for the $.

[Dan]

Changed back to my old battery and deleted the codes. Drove it 18 miles this morning afew times at wot and so far no check engine light.
