Hi,
Dealing with a 2011 Buick Lacrosse 3.6 with Oxygen Sensor codes.
P0134 o2 sensor circuit no activity bank 1
p0134 o2 sensor heater bank 1 sensor 1
P0300 random misfires
P0301, 303, 305 cylinder 1, 3, 5 misfires
"bank 1" is cylinder 1, 3, 5 so I hope that the bank 1 oxygen sensor being bad caused the misfires. I wonder if the reverse could be true too so maybe it's a coil.
What do you guys think?
My dad said the car was misfiring at idle a couple times this week and finally scanned for the codes yesterday.
Thanks
