Hello I have a few questions… have recently bought me a used Mazda 323f V6 with 144hp. I find the car quite great, but the engine is quite noisy?! The car has 120000 km away and is 7 years old. I was already in a workshop, which have noticed that the pre-muffler is light leaking. Does the volume only come from the leaky pre-muffler, or is the V6 from Mazda always so loud? It has its maximum volume at 3000 rpm, then it will be called Then I still have a problem… when the engine is warm and I walk gently off the gas, there is always a short jerk (feeling like a short idle). Is quite funny. Had a Mazda 323F with a 1.5 before and it was quieter and didn’t jerk out? I already had the control unit tested. Has no error codes. I also noticed that the V6 is very weather-dependent? When I drive early, it pulls like sow and at the end of the day. ttag by the sun, he doesn’t do anything anymore. Maybe someone can help me.
