I got my 8 about 6mo ago and have done most of the initial "new to me" car stuff. Plugs, wires, coil packs, new battery etc. I live in NY and since I bought it in winter I haven't been driving it much, when I did I was taking it easy. Nice weather has since let me open her up alot more and I'm getting severe oil dumping around 6500-7250 with loss of all power and huge cloud of smoke. Check engine light flashes for a bit I can hear it misfire when I blip the revs in neutral. The stealership changed the oil when I brought it for recalls and they got oil in the intake which I fixed by cleaning MAF and intake piping and getting a new air filter. Still no change. Is it possible I'm having an OMP issue? Any thoughts are appreciated. Thanks guys.

Somebody probably overfilled the oil. This is easy to do if you don't follow the instructions (warm engine, park car on level ground, wait 5 minutes, check oil level).

I had this happen to me when I replaced my motor. I filled the oil, was a hair over the full mark and thought it would be fine. I drove it around for a month until I really gave it the beans at an autocross. First run, 3/4 of the way through the course: GIANT CLOUD OF SMOKE AND MISFIRE AND OIL ALL OVER THE INTAKE OH MY GOD I KILLED MY BRAND NEW ENGINE!!!

Drained a little oil, cleaned up the intake and MAF, got a new filter, all is well a year later.

I failed to mention that I just checked the oil level and it's just above half. I'll try recleaning the intake and see if that helps, maybe more got in there than I originally thought. Thanks for the help man.

While you have the intake off clean your ESS and reset the NVRAM. (20 brake pedal stomp)

im having the same problem. i changed new coils, thermastat, fuel pump, spark plugs, mass sensor, and i dont know what else to change other than eccentric shaft position sensor next. The car starts but when its warm the rpm gauges drops like the car is about to die. it also surges too. i just want to fix the idle problem. i have some knock sound like metal on metal contact from the passenger side. i already bought engine mounts so ill be replacing that too very soon but i need to figure out how to fix the idle first.

Look up "marble in a can RX-8" and see if your knocking noise sounds anything like that.

Surging idle could be a vacuum leak, especially if you have an OBD2 tool and your fuel trim is reading high.
