Mazda 3 Misfire Sparkplug Replacement

Автокөліктер мен көлік құралдары

My 2013 Mazda 3 check engine light came on. After switching the coil on plug from one cylinder to the other, the problem persisted. The cylinder 4 plug was covered in deposits/fuel. After spark plug replacement the problem returned. Check engine light finally cleared after a can of CRC Intake Valve Cleaner. The problem likely ended up being a dirty intake valve. GDI engines for the win.

    How did you clean the intake valves with the CRC? My 2017 Mazda 3 has a cylinder 3 misfire.

    Saludos cordiales, es que con el Torquimetro, NUNCA se usa para aflojar, porque le dañas la Calibración, solamente se usa en esa posición, cuando hay rosca contraria en aprietes.👍

    I used the CRC cleaner for cleaning of the intake valves, it required someone to help me out by pushing on the throttle to keep the rpm in the proper range. On the first drive, I had a huge plume of black smoke out of the exhaust as I accelerated on the highway followed by the check engine light returning. I brought an obd2 reader with me and reset the code after which the car ran perfectly. My car didn’t experience any problems after the cleaning, but I suppose results may vary?

    El Torquimetro NUNCA se usa para aflojar, solamente se usa en apriete (en torque). En esa posición de "aflojar", es para apretar (dar torque) a roscas contrarias, son menos, pero las hay. Saludos.

    Power drill those bolts off after loosening them much faster

    Do the coils have 3 or 4 pins?

    My plugs at 50k miles on my 2018 3 looked much worse... far too much carbon build up on these cars.
