3 engine codes?
Hey guys. I just got my 05 rx8 today! 131k miles. I went down to autozone it has three codes. p0300- random cylinder misfire detected. p0302-cylinder 2 misfire condition detected. p0506-idle control system rpm lower than expected. Its a little hard starting but seems to run fine. I checked the air filter. Its clean. Any suggestions. TX

K. I'll dig in tomorrow. The dealer said the plugs look newer. I was thinkin of changing the coils too. I seen duralast are 25.99 each. I'll probably get them to see if that takes care of it.

k. I changed the 4 ignition coils. Didn't help. I still got the p0300 and p0302 codes. I ordered new plugs. They will be in a few days. They(autozone) can't get any plug wires so I'm just goin see how the plugs go. Some more info when i get the RPM's up to 4750 the engine light starts flashing. Then goes back to staying on after. Still starts a little hard then takes about 30 second to balance out the rpm's to 1000 at idle.

Well I changed the plugs. But no luck. I'm starting to lead to a coolant leak to the combustion chamber. When I start it a get alot of white smoke for a while till it warms up. Anyone know where this would be?

I'm down it tennessee. It's been humid. Just seemed to take awail to clear out. It could of just built up in the exhaust. Being low down to the ground. This idea coming from a guy being use to driving a jacked up diesel truck But no I didn't notice a sweet smell. No I'm not taken it back to the dealer. It just a small used car deal. No shop. AS-IS.

Update. I used a permant coolant sealer from advance auto. Some stuff nanotech brand $25 a quart. Its a sealant that you flush system than remove the thermistat add product than run 3 hours(I also bypassed the heater core for this step) drain and let set for 12 hours, than flush it out than add coolant and thermistat. Its worked great! Starts right up every day and haven't used any coolant. I've been driving 2 hours every weekday for over a month. Ya I know it's not the mechnics A+ job. But it worked. Time will tell.
