Smog issues....pain in the ***....HELP 98 LS1 with Vortec V-9 aftercooler unit.
Smog nimbies said it passed emissions.
My "system malfunction light" has no data so it failed.
I have been resetting my SES a lot lately.
Several codes coming up.
P0420 Catalyst out of range.
P0152 High voltage to o2 sensor.
Misfire cylander 5.
Local tech shop told me to change o2 sensors and put new plug wires and plug on misfiring cylander5.
I am doing this this week.
I also tryed resetting my system back to the factory settings via the superchips programmer supplied by Vortec.
That test was worse.
It showed 5 functions with no data (o2 sensor/02 heater etc.)
Thanks,
Brett
