Hi, everyone! So just about a week ago I bought an automatic 2004 rx8 with 117000 miles. This was the first time I've ever dealt with a rx8 so I didn't know what was wrong when I bought it. I go test the codes and get p2096, p0302, and p2070. The car seems to have a rough idle with a faint popping noise coming from the exhaust at idle. When I drove it and got it to 5000 rpm there was a clicking noise that sounded like it came from the area of the SSV valve along with the flashing CEL which identifies the misfire. Also something to note is that when I accelerate, the car vibrates pretty badly. Have checked the MAF, checked the air filter, checked the air intake, and put some sea foam into the gas and sprayed some sea foam into the intake. Let me know if I need to provide any more info than i already have. Any help would be great, thanks!

P0302 is a #2 rotor misfire. Weak spark or poor compression can cause the misfire.

P2070 is a cde set because of a stuck SSV.

P2096 is a lean code. The engine can run lean due to the stuck SSV.

Its time to free the SSV, replace the spark plugs, wires, and coils. Freeing the SSV will take some time and patience. Just hope its not the lower tumblers in the intake manifold that full of carbon and stuck. That requires pulling the engine to get the intake manifold off to clean them. Been there, done that.

<br />Sorry for taking forever to reply but I haven't had any time to do anything until recently. I was able to clean out the SSV and get that unstuck. The spark plugs were another story. When i got them off, the trailing plugs were both wet and black and smelled of gas. The leading plugs didn't look as bad and didn't smell like gas, but were also black. I tried to clean them off because I didn't really want to drop $20 a piece on them just for them to be dirty. Got them cleaned, drove it around pretty hard for a while and was still getting a misfire at 5k rpm. Do I just go ahead and buy new spark plugs which I would also just go ahead and buy new coils as well? Or is the problem even related to plugs and coils seeing as I was able to clean them and still get a misfire? Also, what causes the gas to get on the spark plugs?

While you can clean off the spark plugs, you can't fix broken ignition coils. RX-8 is known for having sub-par OEM ignition coils that need to be replaced every 30k miles. Even my Series II with 69k km(42k miles) on the clock has ignition coils with white spots in the back. That indicates bad ignition coils that need to be replaced. Wires may also need to be replaced. If you want to make sure they are good, measure the resistance and compare the resistance to the OEM standards, but generally those last as long as the ignition coils.

And while you cleaned spark plugs, did you check the gap?
