O2 sensor
Computer says p0137 when i do the ignition
test with turning key 3 times. Dnt know if
thats front or back O2 sensor. Sensor is
cheap and sounds very easy to replace from
online research. I can barely afford sensor
let alone 150$ to replace. I was told by
freinds not to worry about it, that i will just
have to put more gas in it. Will driving it like
that mess up engine? Also where can i find
free information on 04 pt cruiser because all
online info i could find has every other year
but mine. God bless anyone who can help.
