New LS1 Owners - Newbie Tech - Question about 02 sensor
06-03-2008, 04:37 PM
Ok, recently my car is running rough from 1k to 1.5k after that it is fine. So I changed out all the spark plugs and wires and there was no difference. So then I recently was on my hand held programer ( Diablo -got it cheap) and notice one of the 02 sensors has low voltage but there is not a SES light. Should I change out the low voltage 02 senor to see if that would make a differnce?

I'd swap the sensors between banks 1&2 first. If the low voltage reading follows the sensor, then you'll know it's a bad sensor.

If it's low voltage, you're either running lean, or need a new sensor.
Regardless, get a set of O2s. They don't last forever.
