O2 Sensor
i am wondering if there is a reliable way to check the O2 sensor on a
89 pontiac sunbird 2.0 OHC. i have read about a few different ways, but
they all say you need a GOOD multimeter. my meter is not that good, it
does quite alot and got me though my electronics course in college, but
it isnt high impedence. any help will be greatly appreciated.
