Question about 2007 Mazda Speed 3 Hatchback

1 Answer

Chat room Randall I have a 2007 Mazda 3 Hatchback. I have a problem with the check engine light. It comes on when i drive somewhere, turn off the car, and then start it again in a short amount of time. The previous owner installed an exhaust system and High powered headlights. I've had numerous dyagnostic tests done (Even from a Mazda Dealer) which have all ranged from buying a new computer, new battery, etc. I got a new battery and it continues to come on. What do you advise?

Engine light comes out for few days and turns of for fews. unitl now that is the routine of my car. i have a mazda3 2007 model. the light goes on and off until the car stops running and i need to remove...

If I were you I would take the car to have the recorded error codes downloaded from the on-board diagnostics. You have a persistent error and the ECU is detecting this and switching on the Check Engine Light. The error might be minor but its effects might be damaging (low coolant for example is easy to fix but risks causing expensive damage if allowed to go untreated). The recorded error codes (DTCs) should provide much more information to make a diagnosis on the root cause of your car's problem.

Just bought an 88 mazda 323. says cat. is clogged. engine sounds ok but was wondering another diagnosis. he says he didnt want me to drive it for fear that if the clog got too hot it would explode and blow...

Well, blow up Im not sure bout that but it could possibly get you stuck somewhere if it is clogged or on the way out.It could cause some engine damage though.I would not drive it if it is thought to be clogged without checking into more.

Mazda 3 tail light on, brake light not on

The bulb actually has two seperate elements in it.
That is why the tail light works fine.

If you take the bulb out you will see the seperate elements.
Change the bulb and it should be fine.
