Also oil consumption has reduced dramatically and probably only needs topping up every 3k miles instead of 1k when new

Right about now there is a sigh of relief to know that I am not the only one having starting problems with my RX 8. The dealership has me believing that I don't know how to start my own car. My RX8 has been to the service department 8 times now, 3 new batteries and they tell me that there is nothing wrong with my car. I do not flood it, it just will not start. I have to jump start it just about every morning and evening. I am very frustrated right about now. Lemon Law is looking pretty solid right about now.

My friend has the same problem too. We tried so many ways to try to start the car. The story was that he removed his pipe and put in a free flow exhaust. Basically he removed his cat. Then he decided to put back the original piping due to sluggish starts in the morning. After replacing back the cat he started it up and it was okay, only still sluggish start. Went on the highway and floored it. Then the car jus died.

So today we manage to start the car using alcohol, injection it thru the vaccum hole on the side air manifold. But on idle it jus died. Took a long time to start but manage to run the engine. So we decided to remove the cat and see if the cat was the problem and on removing it, it was comfirmed that the cat was destroyed. So we are planning to put back the catless pipe and try to start up the car.. But from wat i've read here, there's seems to be no solution to this dilemma.... Any suggestions??

What u guys encountered similar to what i've experienced. Dead cat, idling problem, only rear rotor is working. Still had no idea what's the solution. I just have to wait & keep on searching in the net. Do PM me if u got any updates. Thanx

ask some rx7 owners, they been around this kind of car longer than you.

btw the cat is probaly why the rx8 had like no power

If they say it's flooded, you can unflood it yourself. Look for the EFI fuse, and pull it. Crank the motor for 15-20 seconds. Put the fuse back and start normally. This is a process used on flooded RX7's, so it could work here. If it doesn't work, keep repeating until it starts. If/when it does, it will smoke heavily for a while.

My RX8 floods on a regular basis unless you are very careful starting and stopping the car. The car needs to be started in one turn of the key - no part turns, then let engine settle before setting off. When stopping let car run for a few seconds before switching off. So no quick starts just to move car out of garage and switch engine off again!
We also use the fuse technique you mention above to restart if we have flooding. N.B. No smoking while you are doing this and open garage doors if inside!
My car has just gone in for a recall re a possible fire problem now - what next? Ah well, we will buy these unusual engines!

you can install a fuel cutoff switch

its not really and engine issue, the FD didnt have that problem

LOL, soon RX8's will have the pedal actualted fuel cut off switch in them :P

For a car costing so much you think they woudl have found these kinds of problems and found a way to help prevent/stop them from happening. But no.

every RX before RX8>RX8

There's a Flooding Procedure that Mazda has added to the Owners Manual. I'll scan mine tomorrow and share it with everyone. They also state it in the CD Manual you should have received in the mail.
