My check engine light keeps going on and the last time I had the codes read it was P0304 and P0235 which are the # 4 cyl. Misfire and the knock sensor. I repaced the plugs and wires and the light keeps coming on although it now goes off sometimes and only goes back on after a long drive. I looked at the Haynes manual and repacing the knock sensor looks difficult because the intake manifold has to be removed. Is there another way?
2nd question: the light is now off and I have been only driving to work (5 miles) and I need to get a Massachusetts inspection sticker. How many cycles with the light off are needed to pass?
