my rx8 seems to be running on one rotor....what could be the problem?
its 2004 with around 60k miles, I thought it was the spark plugs so I put in new ones (all 4) as well as the plug wires, and I also tightened a loose ground that I found but it still takes a second to turn on, and struggles to stay on, and I don't see any electricity in one of the plugs. I'm thinking about changing the coils but before I do so I want to know what else could be the problem because the coils are pricey. Also when I press the gas it the rpms dont raise like normal (they struggle and the engine makes a noise like its trying hard.

 

Where do you live ?

Coils are not that expensive, I got mine for 25 bux a pop + tax.

 

change your coils. when was the last time they were changed?

its best to do it all at once

 

Yeah I did a little more research and the coils aren't that expensive, I'm going to try them and if they don't work then according to my research these lower year rx8's tend to flood alot and decrease in compression, alot of people have gotten new motors with the warrenty due this since they've extended it to 100,000 miles. Let's just hope that the coils is the problem!

 

coils and your battery might be weak.

Does your exhaust smell unusually rich? There's no CEL Code thrown for this?

 

Ok so I changed the order of the coils to see if that was the problem because it seemed like one of the rotors weren't working n that was the problem two of the coils were messed up! My personal opinion rx8s are the ride to have they look amazing inside and out and they drive like breeze I think all the people that post negative things comment on really small things such as I did because overall it is a must have car, just treat your car well and it will maintain well change the oil, check coolant, keep everything how it should be, and that goes for every car.
