Hi there,
I have a big problem with o2 sensors.
first thing i did have a air leak, all air intake pipes where perished, changed them, next thing i chanched 02 sensors, all 4 of them,
before i changed those things engine was ideling a lot but now it does it not so often. EC light is still on every time i take off, it comes back next day plus from time to time EML light comes on together with traction control light.
Any idea?
