Hey y'all,
I'm looking for some tips on trouble-shooting why the passenger side bank is not firing on my L.
At idle I've pulled each coil pack connector and the passenger side has no effect on the idle. Every driver side coil had an effect on the idle.
I've hooked a meter to each connector with the key on and saw 12 volts at each.
I know they fire by being grounded. Is there a way I can check to verify the computer is sending the grounding signal?
What about testing the coil packs with the meter?
If I measure with an OHM meter what should my readings be across the terminals as well as from a terminal to the spark-plug lead (spring)?
I just changed the front O2 sensors and it didn't help. Should I check the wiring to the passenger O2 sensor? Can I test the plug with a meter? What should it read if so?
...And can the O2 sensor wiring shut down the bank it's responding to?
The plugs are new.
Thanks for any help.
