I own an 04 RX8 and it seems I have a bad engine. I bought the car in April and it's amazing but it's always had starting problems. I've changed everything, spark plugs, spark plug wires, starter, MAF sensor, Cat converter, O2 sensors, coil pack and it still won't crank like it should. I've taken it to a mechanic who checked my injectors and said they were fine. I also thought it might have a bad computer but he said the computer sent out normal pulses. So is it a bad engine? please help, i love the car too much to sell or trade. I am located near Raleigh, NC do you know of any rotary mechanics in the area?

 

get the engine compression tested and that might tell u alot about whats going on in the engine itself. if u get mazda they have a propper tester that reads all 3 faces.

 

after you do your comp and if it checks out good. look into your coils very common problem.

What do you mean by "starting problems" and "won't crank like it should"?
