Mine liked to randomly not crank when the battery was drained. You probably need a new battery with more cold cranking amps. I got the diehard plat. with the highest amount of cca's possible that we could squeeze in. Haven't had a problem since.

I have a 2008 RX8 with 33,000 miles on it. My car wouldn't start. I got it to the Mazda dealer, and they said there was a blockage in the catalytic converter that didn't allow all the exhaust to get out and damaged the engine. Now they are going to provide me with a re-manufactured engine with new parts. It's under warranty. My concern is how the new re-manufactured engine will work. I'm wondering whether I should do a straight trade of my RX8 for a Mazda 3 (since I have about $15,000 left on the loan). I wanted to get anyone's opinion on what I should do and if they've ever had an RX8 with a new, re-manufactured engine.

I had an '05 that at the time had approx 40k miles on it, and they had to replace the motor (they weren't able to tell me why, they had no idea) and I got a re-manufactured motor, I drove it for about 1 more year and decided that the RX-8 was a money pit and traded it in. I decided that if I was going to throw money down a hole, that it was going to be to a boat or something that I could at least enjoy upon occasion.

The only thing i could think of is maybe one of the cables are not making proper connection with one of the spark plugs or your idle air control valve needs to be replaced (or if you disconnected the battery you might have to bring your car to the dealer or a mechanic to reflash the computer. (NOTE bring to dealer to reflash not any mechanic)

yea disconnected the battery to take off the spark plugs. what do you mean to "reflash" the computer? does the dealer charge for reflashing the computer?

Your car is only programmed to go so fast and to allow a certain fuel to oxygen ratio. to flash your car means your changing those ratio's allowing your car to perform at it's true unrestricted performance. when you disconnected the battery it probably threw the computer off, the dealer might charge $100-$150 dollars to flash the computer. The same happened to me when I changed my battery, when I slowly came to a stop no problem (but i could see the idle needle go down slightly) but when i came to a fast sudden stop the car would shut off. I hope this info helped good luck.

Ok thanks man. I have a other question..... would the car turn off if it had a radiator or thermostat leak problem? Because I took to my mechanic told me it had that, he said that's why it turn off.

It's possible if the thermostat locked restricting antifreeze flow, or if you had a leak anywhere like a hose that would cause your car to overheat and shut off any time, not when you put on your brakes.I'm assuming your car was working just fine until you disconnected the battery to change the spark plugs so i don't think it's the thermostat or radiator, (but that's only my opinion) I don't want to mislead you about the mechanics honesty but the mechanic could be right he probably found that other problem while checking your car.
