I have an h2 2006 had knock sensor issues fixed that then tuned it up with new plugs etc got some 87 oct gas
oxygen sensor bank 1 sensor `1
i just fixed sensors what is going on
well i got my new sensors in had to order special wrench
coming tomm
i had a idea i will go fill it up with 93 oct to just see for myself because of no way
everyone says this has anything to do with oxygens sensors
afterwards, no engine light truck runs great what a difference
no engine lights at all now ran it over 100 miles.
