Engine Sputtering?/Fluttering? when accelerating
This is only about the second time ive posted on here and ill say like i said before i dont know much about cars or the RX-8.
When i accelerate at the low end (around 5-10 mph) my car shuudders or flutters like im hittin a ton of rough ground or something. Also when i first pulled my car out today it started jerking on acceleration like when your messin around tappin the breaks hard. i have no idea whats going on. Any help would be greatly appreciated.

From a basic description, it could be a fuel cut, ignition cut, air cut, clutch grip problem (if MT), torque converter problem (if AT).
If it's a fuel, ignition, or air flow problem, it could be ignition failurer, a vacuum leak, MAF fouling, e-shaft sensor fouling, and a few other items. Going to have to be a bit more specific for a more specific diagnosis.

Questions we CAN answer:
Most issues that the RX-8 faces are easily answered when you post detailed, descriptive, and accurate explanations of what symptoms you are having with your RX-8. Many of our issues share common symptoms with at least one other issue. Several of the really common issues share MOST of their symptoms with another problem. So when you post: "power loss?" We can't really tell you what is going on. We can only throw the book of possible issues at you for you to figure out.
The amount of assistance you receive is DIRECTLY associated to how much detail you provide!
So what do you need to share?
A) Break each issue you are seeing out by itself. For each of these issues, detail what RPMs it occurs in, and what RPMs it doesn't. Detail how much throttle you are giving when it occurs.
B) Detail what the ambient temperatures are that you are seeing, what the gauges are doing.
C) If you have a CEL, GIVE US THE CODE! (most auto-parts stores will pull the code for free for you. Otherwise, you can buy a code reader for LESS than the dealer's diagnostic price, giving you a discount on that one, and free code pulling for the rest of the device's life, across every car you own) (Hint, search with Google and site:rx8club.com <CEL> before posting. You will probably find your answer.)
D) Detail any possible modifications or repairs that have been made within the last 3,000 miles, even if it seems like it's not related.
E) Detail the age and mileage of the car, and what maintenance history it has been on. NOT just "it's gotten regular maintenance" because there are wear items that are not part of "regular maintenance" for dealers and most shops.
F) Since many issues are ignition related, and you are going to get asked, give us the mileage and age of ignition coils, wires, and plugs.
G) Detail out when it DOESN'T happen. This is just as critical as when it does!
Another thing to keep in mind is that unless you are being a complete jackass, and unless the person responding to you is ignorant about the issues, our answers are going to be pretty accurate, if not dead on. Even if you don't like the option. We have no stake in your finances, no stake in making money off of it. We DON'T like to see unhealthy or busted 8s. So if you choose to ignore our recommendations, do so at your own peril, and don't come whining to us that you shoveled money at the problem that was completely unneeded.

Its an automatic transmission. I took it to the mazda dealership and they said i needed plugs and wires and a zoom clean. I did all that and the engine light was off for 5 minutes after i got it back from them. Now its driving even worse and they are talking about replacing my intake becasue of my shutter valve?
