Hi I just got my spark plugs changed on mazda 3 2006 1.6 engine. But i am not feeling good acceleration like before and shaky gear shift? What could be the cause for this? I am really worried. I diagnosed and found out code p0123 throttle sensor issue. But the car was running smooth before the change. Could you give any advice?
Hey I have a Mazda 3 2006, same engine as this. My engine light was showing and I was experiencing small misfires so I took it to a mechanic to diagnose the light. He told me his machine was reading a faulty coil. I changed the one coil and all spark plugs but my engine light is still showing. Any tips on why this is? Thanks
Thank you for the reply, I just solved the problem, I didnt see that there is one more bolt in the centre of the valve cover,..now I already replace the valve cover gasket, now I have one problem there is a white smoke coming from the engine after I replaced the gasket., im not sure if that is because of oil residue from the dead spark plug or it needs to be tuned up.
