Question about 1999 Toyota Corolla
My engine light is on. I have checked and know that it is the misfire of the cylinder 1 and the code is p0301. I have changed the spark plung, spark plung wire and igition coil but the code still comes back. Is any one can help me to fix the problem, please?

Were your plugs oily when you took them out?The reason very often is leaking valve cover gasket. If the gasket is leaking even slightly in the plugs cavities, the oil will ground the spark plug shorting the circuit and throwing misfire code. That is why, the problem reappears when you replace your spark plugs, injectors and ect. New valve cover gasket solves the problem.
