Hello all,
I just bought my first RX-8. It had the check engine light on when I bought it so I read the codes. Evap problem, O2 sensor problem, and two misfire codes. The car also gets very poor mileage and exhaust smells of un-burnt fuel. I pulled the spark plugs and they looked fine (I put them back in the right order trailing-leading). I then checked the ignition coils and found one had no continuity on the primary winding so I replaced it. I then checked the fuel injectors to see if any leaked under pressure. None did. I also cleaned the crank position sensor. I put everything back together and when I restarted the car it reved to 4krpm and then refused to fall to idle. It keeps jumping between 1000-1400rpm and backfires a lot. There is also a metallic sound in the exhaust, I banged on the second cat and it rattled so maybe broken. Kind of sounds like an internal piece is broken in the muffler too. No check engine light comes on. Higher RPM sound good. I did not run longer than 15 seconds. I could have gotten the fuel injector connections reversed too. Any ideas? thanks.
