Question about Mazda RX8
Hi, Please can anyone help me? I've got a Mazda RX8 2004 231ps manual . I've stopped the car for about 5 to 6 weeks and it got flooded. I've manage to start the car but now the warning engine light is on and sometimes the coolant light comes on as well. Also I feel the car loosing power. I've done the diagnostic and it comes up with code P0562 which is System voltage low. I've cleaned the spark plugs, I've tested the battery, even known the battery light never came on,and I've tested the alternator as well but everything seems fine. Does anyone knows what else could it be? Many Thanks Bruno

yes, this is the case of a failed throttle body, in which case it needs replaced, the car is getting too much fuel causing the high idle. this needs replaced asap. you could proably find a small independant honda shop that could do the work for less.

I'm guessing that you've tested the actual current output of the alternator then. I'm assuming that the output is between 13-14Volts at the battery when the car is running... If it's too low, then it's not charging your battery at all, too high, and it's frying your battery.... Another thing that can cause this is if you have a short in your electrical system.. that, however, will be difficult to narrow down...

Ignition timing could be off, the plug wires and firing order may be scrambled, there could be a large air leak into the intake manifold, the EGR could be stuck open, the fuel pressure is too high and flooding the engine through the cold start injector, the MAP or MAF sensor is faulty, very dirty fuel injectors, idle air control valve defective, the engine coolant temp sensor is faulty (stuck at full hot).
