The dyno makes his problem obvious. It's not the cat. It's the auxillary ports not opening. Notice at the EXACT point they should be opening to let more air in, power flatlines. It peaks really quickly before this but not enough so to be an issue. Right above where the variable intake valve opens and effectively shortens the intake runners, power rises again, as it should. The cat is not causing this. Even the Mazda dealership mechanics would have caught that problem. If it were the cat, power would not flatline and then slightly go up again later. It would hit it's peak and then start to fall off again.

Richard, if you end up getting your car back with no issues resolved, just reach down and unbolt the auxillary port motor on the passenger side of the lower intake manifold. It's the only thing there. Reach in and see if you can turn the little gear by hand. If you can, the rotatins sleeves aren't stuck. Then apply a quick current to the motor to test it. If it doesn't spin you know the problem. If it does spin then you need to see if thee is a solenoid issue before this motor. It's easy to do. I know Mazda should be fixing it instead of making excuses and pawning it off on someone else but this is a very easy thing to check.

another way to handle it would be to use the power of our club. smack them with a couple hundred phone calls asking "why dont you look at richards tertiary ports?"

Agreed - there are lots of possibles....

Tell them to open up the engine and check for the problem. Tell them that if there's no problem you'll pay them for looking. See what they'll do. If the dealership techs don't know how to recognize the problem (ie their readout would say send car to Mazda development) you might have to take it to a private shop if Mazda won't just give you another car for free.

Good idea Fred. That is what I should have done over the weekend, it would have taken less time then three trips to the dealer. It would be easier on my gut.
It would be easier on them too, because now I have to wonder if there aren't 25,000 Rx8's out there having this same problem. Thus causing the lack of power anti sales reputation working overtime. Who knows how many guys are just sick of their cars under performance. They took it to the dealer and they put it on their computer then send the guy home without fixing it. The guy sells his car because he didn't get what he paid for.

How many power problems can Mazda handle?? All self inflicted. When your kid blows your doors off with his stock Civic do you think there will be repeat buisness???

I handed them the problem on a plate. What they should do is fix it and send out a note to dealers that this might be checked on cars with power problems. I'm not saying Recall, by all means avoid that. Avoid it by checking it now.

All 8 owners, go out and make a full throttle pass. Pay attention to the feel of the power curve, if it stops pulling at 6200 look at this. If it starts feeling like a electric motor, just sort of keeps going up the RPM scale but not pulling hard. My car feels like it needs a boot in the butt to get anywhere near redline. I never tried pushing it to get the shift buzzer because it feels like it needs to be shifted long before that. Anyone else get that feeling???

Mazda is sending a "file" over to Galpin, whatever that means.
My spelling and typing get even worse when my blood is boiling.


So before we all march on MNA lets give their tech center a chance.
They said they were having the dealer call the tech center. Why duidn't they do it by themselves. Know why? Because they think they already know everything. How can they know everything, when "We" (as this forum) know everything?

You can allways try.......... Nemesis8,,,,,,,,,,,,,,, list of possible problems and give Mazda a scientific way of finding a solution to your woes . :D

Mazda Mechanics trouble shooting at its best .

Richard, I am curious what gears you feel the lack of power past 6200?....is it in first all the way through? I know my car has that pull past 6500 or so in first, and it gets less pronounced as you move up the gears, but I can feel it in first and 2nd, then 3rd tapers off a bit. Sorry to hear about your woes, but hopefully they get it figured out?

rotarygod

His dyno chart shows where the problem is. It's not gear dependent.

richard - maybe you can get them this new diagnostic tool. i have one and it seems to work pretty well. using it i seem to be right AT LEAST as often as the service guys

They say my car is done. I havn't gone to get it yet. They tell me they did the latest reflash. That is all that it needed, they drove it and it is OK. They did nothing else, they will do nothing else. I talked with MNA and they sent the dealer a file who then claims they don't know anything about an e mail from MNA.

They tell me they couldn't imagine what Mazda would want them to do. There is nothing else because the printout says everything is working.
So, they will not fix it or they fixed it but don't want to admit it, at least not to me. My gut tells me that they did nothing until MNA mailed them, then they did it but don't want to tell me I was right and they were wrong. A service manager with an ego problem!!!!!

Richard it can take a couple of weeks for what they did to show up where someone can read it.

That ruins my day. As if it wasn't already. I'm going for a Bloody Mary.

Hey,I could leave it there. I have my Caddie. I don't like driving the 8 if it is still fuc&*d up.
I'd hate to leave it there for two weeks only to find out it is fixed.

Have you driven the car since they flashed it?

There was an issue on early cars with secondary injector trip-in

The file would have been installed with the new flash.

Edit...

You ask in a earlier post about having a bad converter..some of these cars flooded on the lot and no claim will ever show. Some dealers just took it on the chin and changed the plugs etc.

Richard Paul

I do not have the car back yet, I will get it in the morning.
You saw the prior list of service. I had Gomez look at it and he said it had all the new flashes.
That may have been only up to M though. What the hell do I know it could have had "A".

Aseras

pop the hood or look un the door sill for "authorized modification" stickers and get the higherst campaign number you see ( like MSP-XXX ) that'll indicat what flash you are on. I have about 7 of these stickers on my car now.

G8rboy

Unfortunately not all dealers do that... I've had several TSB's done, a recall, and 4 flashes, a not a sticker to be found anywhere (I'm not complaining though- I'd just take 'em off anyway).

MSP 04 mean anything?? Date done was 2/15/05

If the bloody car was there last sunday then I could have checked the exact CalID with sCANalyser. And did some logging of the MAF etc.

Cheers,

That was the campaign for the 'M' Flash...

Then that was what had before today.

Gomez

Yeah Richard, you will have whatever the dealer had in his WDS at the time. Probably the "N" flash. You really shoulda had the car there for Hymee....... . You weren't fair dinkum and it just wasn't cricket.

Gomez.

There's that "fair dinkum" again..

Get the car back and see if the injector stumble has been addressed. After that we can see if something else needs to be done.

It's 1:27 and I'm out like a the fat kid in dodgeball.

Translation please.

I don't think it is injector stumble. You said that was secondary "tip in".
I thought the secondarys came in somewhere in the 3800 or so range.
I didn't think the aux ports had their own injectors.
Truth is I don't remember where the hell the injectors are.

It is just so obvious that this happens at exactly the point of aux action that it can't be anything else. Or can it?
Do they have this intake so finely tuned that it falls off right there if it doesn't get more air? I mean it drops not tapers off.

Hell, I'm just going to get some rest and not think about it until I pick it up.
This is usless mental ************ since I haven't driven the car since they worked on it and they could have fixed it without telling me.

Sigma

Judging by the majority of the Mazda techs I've come across (no offense to snap-on and others) they could have fixed it without even knowing it themselves.
