Gents: CEL caused by oil overfill. Drained oil & it cleared CEL... BUT?
Resolved: 11.5 year old RX-8 still trouble free
Okay, I'm not sure how his happened, but there was about a quart overfill on my 2005 6MT Rex.
I've not only had no reliability issues, but this is the first CEL my 8 has thrown in 11 1/2 years.
So I go to a friend who helps me out (and I help him out on stuff), and he pulls the code which reads:
"P2070 Intake Manifold Tuning Valve Stuck Open Bank 1"
So we proceed to drain 1 quart of oil, so that oil on disptick is just below full level. He and I agree that since the motor isn't misbehaving, I should go and rev the sh*t out of it on a long ride, and try to free up the stuck valve (IF that's the real issue).
So only into 2 miles of driving, the CEL goes away. I shut down the car and wait for about 15 minutes, and the CEL does NOT come back on.
I proceed to drive the car for another 10 miles or so with no problems whatsoever, on surface roads, highways. etc. No idle issues, strange noises - nothing.
Here are my questions:
Should I check the MAF Sensor?
Should I check the air filter to see if oil soaked it due to the overfill?
Should I run some Chevron Techron Concentrate (black bottle) through a tank of fresh gas now?
What other potential problems could this have caused, even though I made sure to drain the overfill literally within 20 minutes of the CEL coming on, the car is running great, and the CEL hasn't back on with the oil at the proper level now?
THANKS BROS.

The intake valve stuck open code shouldn't result from extra oil, so don't be surprised if it comes back. These things happen, the valves clog up with deposits. Search for SSV cleaning, requires taking the intake apart a little bit, but nothing too crazy.
Okay, thanks for the replies.
The CEL went away as soon as I drained 1+ quart of oil.
It hasn't come back.
Loki - I will read that thread.
I appreciate all the input/feedback guys.
The car is running beautifully.
I will keep in mind SSV cleaning in case CEL comes back.
(there was no oil in air filter)
