"are you still experiencing the oil into the intake?"

-when i first discovered it..i cleaned it flipped the filter 180 and drove it for around 200kms..pulled it apart and the filter was covered again and the intake tube was full!!

"could it be screwing with the maf causing your limitor problem? or if you oil pressure is low or oil level is low(which since you have the bad pan and oil loss this could be it) could be causing the car to tune itself down. "

-maybe my oilpan is causing the problem under heavy accelaration???

-I have only pulled the code twice.... with several kms between occurances.

if it gets the same code several times in a row it will go into limp mode.

-it doesn't throw a "hard code" just flickers the engine light kill power and then comes back

this is going to sound stupid, but it happened to me.

how much fuel do you have in the car??? i tried to make my high speed runs with the yellow light on. you know lighter and everything.

everytime i hit about 115mph it would throw a cel and slow down.

filled up with gas, 20min. later hit 135 with no problem.

just my uneducated opinion but you have got to get them to pull the codes and locate the source of all the oil. that is definetly a BAD THING and to me it all seems connected. the oil is coming from or going to somehwere the sensors don't like and that's causing the codes and temporary loss of power.

Happened to me too, on the weekend. Pulled out to go to work and the yellow light was on.... anything more than 'usual' acceleration caused the light to flash, and power to stumble.

Disconnected the battery to reset, and all is fine, hauling *** today with three passengers, 9000 revs, no problems.

My personal best in this car was 244 kph, ain't no limiter here!

perhaps your car misfired? mine seems to do it occasionally at 7000RPM, decellerate and resume at 8000...then the CEL light comes on for about 30 seconds flashing and then back off...i've had it reflashed twice now...

Mr M

This is getting confusing, was it definitely your Engine Check Lamp that was on, or your oil lamp? If it was your engine check lamp then there should be a code, weird. How modified is your car? There are TSBs for MIL on and oil lamp on, but that doesn't explain your power loss.
My two guesses would be a metering oil pump problem, which may explain the oil in your manifold, or that your auxiliary air port and one of the injectors is not working intermittently. The metering oil pump is the life of the rotary engine, so you should have it looked at immediately.
Or it could be something simple, like a loose connector. I think it would be best to leave the car at a dealer for a week or so to let them find the fault.
Hope this helps.

Well had the car at the dealer all day.....
here's what was found:
first off the techy was dumbfounded when he pulled the vacumn line apart and found it to be presurized!!
a vacumn silenoid was malfunctioning(the one located on the intake prior to the airbox),and 2 check valves where plugged.
check valves where in stock, but silenoid is 3 weeks from japan.
They installed my new oilpan...which may or not aid in the oil problem...
the vacumn lines are presurized they can't find out why...the oil is being blown into the intake..covering the mass air sensor..throwing the ecu into limp mode.Which in turn has affected by throttle response due to improper signal from the (covered in oil )mass air sensor.
They still have to check my tps in conjuction with the readings from the mass air sensor and do a compression check.
I expressed my concerns of the motors compression...if the vacumn lines are that presurized while the motor is off what is the presure in during a running condition???
But they want to do everything in steps and wait for the order parts before going through the rest on the car..which is understandable,but annoying.
When there is a demo rx8 on the lot covered in snow they could pull the ordered parts from, or at least check the readings and compare..
i'll keep you guys posted..thanks for all the info.

Could that line pressure have anything to do with several people having oil in the intake hose??

Mr M

Still sounds strange to me. I looked at your website. Is your 8 modified (intake and exhaust)? I look forward to hearing any new information on this.

On US Spec cars, there is no limit other than the 9000 RPM rev limiter.

"Drag Limited" means given local conditions, at some point (estimated at sea level to be in the 160 MPH range) the engine cannot push you through the air any faster.

Personally, I've had mine well past 120 MPH with plenty of "go" left :D

zoom44

see that? i said oil screwing with the MAF! maybe i am learning something afterall!:D

Mazda Monkey

Automatics are speed limited to 124.5MPH

My bad. On the US 6MT cars :D

Hey just got back from the dealer...they found a few things wrong.
here's the comments:
secondary intake tube solenoid valve is defective..seized.
When the mechanic pulled the vaccumn lines off..it was presurized!!!.
Further looking they found a check valve plugged.
Here's my theory for the temp. engine code under heavy accelaration(thoughts of a governor, and confirmed by mazda??)
With out the new oilpan on under heavy accerlartion the oil runs back in the pan,causing the oil to be sucked up into the intake tube...so much is blown into the intake tube that the mass air sensor get coated in oil...thus causing the ecu to get confussed and throw codes.
Put this into the equation along with the faulty solenoid valve limiting air at high rpm
HENCE MY TEMP. ENGINE CODE AND PROBLEMS.
reading the forumns i seam also to be one of the higher mileage cars in canada??18,000kms.
thanks for all your imput.
i will await the japan ordered part and hopefully this will correct the issue.

The dealer installed my new pan and i had new plugs put in.

I'm new to the site, so I am surprised there is so much speculation on this post. I live in Japan, and my rx-8 therefore is Japan spec. ALL japanese-built cars have a speed limiter at 178 kph, or about 115 mph. I think the car in question was in OZ, but having the exact speed limiter sounds like too much of a coincedence. I have had my rx-8 (sport model with 6-speed) for only a little while. I must say it absolutely rocks. Not to mention, I can fit two surfboards plus a cute surfer chick inside the car. Sure a little more power would be better, but I drive it up into the mountains near mt. fuji on hairpin turn after turn, and it takes them like a rock star at 80 kph - traction control blazing. I am a little concerned about the govenor, 115 mph max is kinda a waste - it makes hitting a track out of the question. Does anyone know how to remove the govenor? I would need to be able to replace it, since removal not only voids the warrantee, but it makes it impossible to register the car (called a "shoken" here). Hopefully it is electronic. thanks.

zevans

Not necessarily... most I saw on my track day was 108, and I was coming out of the previous corner faster than most people.

I'm sure there must be a way around the shoken... you think every R33 V-spec in Japan is still limited to 115? :D

jason123

I don't know what a Japan v-spec is, but all production cars made in japan have the 178 kph speed limiter - this is a Japanese law. doesn't apply to foreign cars, which can be street legal with no limitation. there is also a large tax on imported cars, so if you want to drive fast, you need to pay up. must get shoken every 2-3 years, and they check for the limiter. so if you want to get around it, you need to go to a crooked shop (not so easy for foreigners).

I had mine at 221 km/h (138 mph) for like 10 -15 seconds and it would not go up in a big flat straight... Anyone has a clue why?

I was in 6th gear like at 7 K Rpm, but the needdle did not keep going up

93rdcurrent

Ditto

zoom44

easy - you dont have enough power in that gear to overcome the drag at that speed. find a hill to go down or shift up from 5th to 6th later. or find a nice tail wind

zoom44

was thru terwillger on 5 here? i know one guy (monte) who had his over a hundred thru there.

93rdcurrent

Nope I was on my way home from Bellevue on I-90. I was near Ellensburg on the straights and had an irritating Honda Civic that refused to get out of the fastlane and their headlights were in my driver's side mirror. So I gassed it up for a bit and got wayyyyy ahead of them. No more irritating lights... :p

top speed is actually when you hit redline in 5th gear... not enough oomph in 6th gear

I was in 5th gear at 8300 RPM
