It was dark, I was on the driver's side of the car, he leaned in from the passenger side, and did something to make a "flapping" sound and asked if it could be that sound repeating itself really quickly. So yeah, I would guess he was moving the secondary valves.

I like this idea much, much better than premixing as it should provide the proper oil amount to the engine with a better quality (for the purpose), cleaner, and cleaner burning oil. This has to help reduce and might even eliminate the carbon buildup issues.
Let me know if others have done this and what they think as I am really interested in doing this mod.

Ok, wierd sounds that ive herd, a rattle in the exaust, I still hear it and havent empteyed it out yet though but I now its pieces of the cat or the stock exaust, ive gotten mine to the point of glowing all the way to the tips, I think I rattled a couple pieces of baffle off to add to it, gona check my cat in a few days but I dont see my cat being clogged. As for shudder valves, some times on a stock car you can here them slap open, that can be cured by putting a restrictor in the vac hose going to the highest valve. Motor mounts have been giveing problems also.

Rhythmic; so far we haven't found any cure for the noise. Where does your sound come from? Run a couple more tanks and see if the noise goes away; if it does it's most likely your gas. Also, feel free to join the party in the Marbles thread and post your observations. We've found that not everyone has the same marbles.

The problem with bad gas is youl get a ping or tsick sound. Its hard to get a naturly aspirated rotory to ping, it would mean either a little water or really bad gas, so bad youd smell it.

Mine went away for a few days after the recall then came back. I feel it was the PCM recalibrating. I cant run reg unless its cool out . If its over 80 deg, I have to run prem or it will ping(MIAC). Going to try Carbon Cleaners then try reg-fuel again, it ran the first 20k fine on reg.

I'm not running a premix oil to lubricate, I'm running a Carbon-Cleaner. I'm going to try to reduce the carbon buildup so it wont ping on reg 87 fuel(it did not the first 20k). I feel the rich mix to try to make emissons are the cause. I have to run prem now and will til I dont need it.

For a good one-time cleaning use BG44k and if you want something to add to every tank to keep it clean use FP60 from Lube Control - both are great products and you can get much info/endorsements at the BITOG site if you want to look into them.
FP60 is supposed to contribute to a more efficient combustion as well (and more MPG) - may be able to return to 87 octane while using without pinging if that is your goal.

The BG44K & FP60 are two on my list I'm allso looking for Chevron Techron, have you seen this one? How many others have had good luck with these getting rid of the detonaion marbles. I will run a tank of prem this weekend with one of these in it, then add reg Monday and see if the 1 tank did any good.

i don't understand why some of you are even using anything less than premium!!!
this car should ONLY run on PREMIUM!!!
carbon buildup will occur on engines using high octane fuel.... it will be much worse if you use cheap gas!!!

But, you could probably get by with a cheaper brand of premium, or possibly 87 or 89 octane, if you run Lube Control FP60 as greatly helps combustion and has great cleaners which may reduce the dependency on premium fuel.
Also, Carbon buildup has nothing to do with "high octane fuel" - carbon is produced by the burning of all fuels, independent of octane, and is increased in rotaries by incomplete burning of the fuel (why we get worse fuel mileage) and the oil addition from the MOP. Carbon buildup also creates more detonation issues - the old vicious circle.
These carbon-producting characteristics of the rotary are why it is vital to get good cleaners in your fuel either by running premium gas all the time, adding good cleaners into the fuel, or both as I do.

I would go with a cleaner you can add along with the premix into every tank, like FP60 (or the upcoming FP3000). FP60 is added a 1oz per 5 gallons, so about 2-3 oz per refill is all you need and a $33/gallon, does not cost much to run and works great, including helping MPG.
