I did uses the Bosch +4 , Have been using them for 4 years.
Plugs were what I was thinking, dont think they have ever been changed. When I took the old plugs out One of them was covered in oil and another was damp. Meaning burning oil. Since I live in ONTARIO I also have to do an emmission test by tommorow, what are my chances of passing? If I reset the computer will a code reader still be able to pick up any codes or does the light have to be on. I dont want to do the test with the light on. It usually takes 3 or 4 days for the light to come back on.
