Hi together,
Iīm sorry, i donīt have enaught posts to write to the main threadpage, but i nevertheless want to ask you something.

On my driving route to my office i usually drive without any traffic jam. On this direction the car drives normally. I am able to speed up in 6th gear with slow but normal acceleration.
On the other direction from my office to my home, sometimes i stuck in traffic jam just after starting up the car for about ~10min. After the traffic jam with sopīn go traffic, i have the feeling that the car has huge problems to hold the speed in 6th gear at an constant level (a bit exaggerated. But i have to throttle down the gas pedal to 90-100% to hold speed).

Is there an known problem with this behavior?

Thanks to you all

There is a rather large list of possible reasons for "power loss".

What is your maintenance history like?
* RX-8 critical items, so if your only answer is "oil changes every X km's" then it would imply you are ignoring everything else.

I baught the car just 3000km ago from an "Mazda Partner" and the car always has been maintenanced there.

So that tells me that it's been completely neglected beyond regular oil changes.

Here is the list you need to address:

I am buying it! What should I address first?:
Generally, the more history on these items you can get from the prior owner, the better. These are all RX-8 specific. They are in addition to typical items like brakes and tires. Every item on this list is on it because it either fails regularly OR a failure of the point will result in significant cascading damage and costly repairs.

Car mileage over 30,000:
- Replace Ignition coils
- Replace Plug wires
- Replace Spark plugs
- Clean MAF (mass air flow sensor)
- Clean ESS (e-shaft sensor)
- Reset ESS profile
- Clean power steering connections
- Clean battery terminals and clamps
- Replace transmission fluid
- Replace coolant (Mazda FL-22 is highly recommended)
- Replace air filter
- Replace brake fluid (fluid in the brake lines AND the clutch line)
~$300 USD in parts if you shop smartly.


Car mileage over 60,000:
...all above, plus...
- Clean all chassis electrical grounding points
- Replace accessory belts
- Clean OMP lines
- Replace rear differential fluid
- Replace thermostat
- Clean / Straighten AC condenser fins
- Clean / Straighten oil cooler fins
- Inspect catalytic converter
- Clean / Inspect intake valving
- Consider / inspect all points in 90,000+ as well, many items fail early
~$130 USD in parts if you shop smartly.

Car mileage over 90,000:
...all above plus...
- Replace coolant bottle
- Replace radiator hoses
- Replace radiator
- Replace front O2 sensor
- Replace motor mounts
- Inspect clutch pedal assembly for flex / weld breaks
~$900 USD in parts if you shop smartly.

Obviously if you get information about any of these items already addressed, it will help to reduce the list / cost. Get as much certainty as you can though! All cooling related items can cost you your engine! Even as soon as the same day you take the 8 home with you. It has happened more than once. The rest can be just as critical in how much it can cost you.

Note: This isn't a dealer's maintenance list that is filled with questionable fluff. Every single one of these items is something that typically fails in that mileage range, and for each item, if it fails it will either A) strand you, or B) cause significant and costly additional damage.
