RX-8 Rotary decarb part 1
Decided at 25,000 miles, it was time for a decarb. Used seafoam rather than Mazda's cleaner. I placed two tubes in the can of seafoam, and ran each line to a separate vacuum port, so I could do both rotors at the same time rather than separately. After sucking up all the seafoam, let it sit for a little over an hour. Then I put a cup of Idemitsu in the empty seafoam can, used the two tubes again, to help lube the rotary chambers during initial startup.
Afterwards, low end torque seems improved, and throttle response is way up, most notably when starting out from a stop. No bogging down, other than when I clutch poorly ;). Idle is PERFECT. While idling, there's no vibration from the engine whatsoever. Like new.
And as expected, the check engine light came on afterwards, and stayed on for about a day before going out.
Update 03.08.12: Some have questioned how well the Catalytic Converter has held up after the seafoam cleaning.. First off, 14,000 miles later, it appears to be fine. No power loss or other symptoms of a failed cat. However, that doesn't mean that the life of the cat hasn't been shortened. Looking back, I should have disconnected the cat before this procedure, and will do that in the future, and would advise anyone else with a cc and doing this procedure to do the same thing.
For those that have questioned whether or not I should have introduced seafoam into the engine at all: Mazda has a decarb procedure of their own, using a product similar to seafoam.

Rx8's innovations in the handling department mostly,examined by Best Motoring and explained by Mazda's Chief Developer.The Rx8 features numerous enhancements when compared to older rx7's which give it an edge on the handling section againt it's older rotary brothers.Increased body rigidity,revised and redesigned suspension from scratch,lower and further behind egnine placement,lightened rotors,lighter flywheel,carbon fiber driveshaft,side ports,longer and wider wheelbase for better handling stance are only some of the major improvements over the older rotary models.

RX-8 WARM START PROBLEM! *UPDATED*
Ive since then took the car and had it fixed. Turns out the starter wasn't turning quick enough and causing the car not to start. Spark plugs were pretty bad too.They said the compression was a little low but not enough to worry about i guess. $800 later... it starts right up.
So I've owned this car for about 2 1/2 years and it has been fine till about a few months ago. I noticed it took my car a little longer than normal to start but never really thought anything of it. It takes about 4-6 secs to start cold but if the car is warmed up and i try to start back up, its a no go. dealer said it sounds like compression loss but cant be sure till they look at it. if anyone knows what might be going on or had something similar please let me know in the comments. id appreciate it.
