PO307 0 Cylinder 7 misfire
my SES light came on the other day. Had 2 codes PO156 & PO307
PO156 is an O2 sensor BAnk2 / sensor 2...after the cat
I bought a new sensor- still have an SES light.
now I only have the PO307 which is cylinder 7 misfire...
Any ideas...
just replaced the plugs 5000 miles ago...
