Ok some of you know my car broke down in tx last month. My car would not accelerate above 6k rpm it would start bogging and choking till it died. well i came up w/ the idea that it was my mazsport ignition, so i replaced it with my oem coils which are pretty old, and that fixed the problem for a little bit.

Now i am having the same problems again, the car will just cut out like a clogged cat or something past 5.5 6k rpm. Now I'm thinking its just my old oem coils starting to crap out now, and if i buy the bhr ignition it should be fine. Now ive noticed that it really dont start cuttting out until the car has been running awhile and if i start redlining it thats when it starts to get bad.

Now im tryin to figure out what else it could be before i go spend a bunch of money and not get the problem fixed *even though bhr ignition will be put on either or* I had a compression tets done and its 8.0 across the board so motor is good, and it only has 10k miles on it. I have a mid pipe so the cat being plugged is out of the question. The dealer just flashed the car with the latest flash.

I just put new spark plugs in ti about 5k miles ago, but to be safe i think ill put new ones in again w/ new ignition. What do you guys think about this whole thing? I just want to get to the problem and know how to fix it. oh and theres no check engine lights either.

Well, since you have no cat....

The problem has to be either fuel or ignition.

Ignition is a cheaper, first place to start since we know about the OEM coil longevity issues.

Do new wires at the same time.

Mazurfer

So it's not an ignition(start-up problem) in that sense.
Based on what you said.......let's see.............I'm assuming your plug wires are good.....need to check those. Make sure they are on good, but you might want to just replace anyway.
Is it possible you have some sort of an airflow problem? How long since you cleaned or replaced the filter?
All the small hoses connected up good on the intake?

If I think of more, I'll edit this. BUT...............it's funny that after you switched the coils you said it got better for awhile. Could you just have a plug wire backing off and not secured right or breaking down with heat?

Damn it Silver06.........you and I were typing at the same time!

wassup_nuthin

Well I dont think it is the plug wires since I first had the mazsport in which are completley different plug wires then i switched back to the oem coils and wires, so the coil are old thats why i bought the mazport at the time, and the wires are old too. the wires are secured nice and tight i made sure i heard a click before i left them alone when i put the oem coils and wires back on.

This makes me feel a little better since most likely my old coils are just starting to go out, and
hopefully the bhr will cure my problem. But lets say after the new ignition i have the same problem, then what? New fuel pump?? So far it only does this when the car is been running awhile but it will problably gradually get worse as the coils worsen if in deed it is the coils * which im almost positive it is* just needed some other opinions.

airfilter is a new k&n w/ airbox mod. all hoses are secure.

Mazurfer

Crap...................you ain't making it easy. Oh yeah, I should've realized you would've probably swapped the wires back with the coils. BTW......I still have the Mazsport ignition system in mine and all is okay. I will eventually end up with the BHR, but I'm fine for now. I'm also assuming you are NA?
Yes, I guess it could be the fuel pump(heat related?????) probably not the fuel sock with what you describe, but maybe it's restricting the flow required??????
Keep searching on here and see what you come up with. I know I just read some posts the other day with somewhat similar issues.
I'll see what else I can think of or find.
Do you have the sheet or info to tell you how to test out the coils? If not I can give it to you.

what exactly does it do after 5500 rpm? Does it actually bog down and die?
Any CEL's?
this is sounding like a fuel delivery issue

wassup_nuthin

it just cuts out almost like a rev limiter and i have almost zero power. then if i keep pushing it, it will bog soo much it will die.. im pretty sure its my coils but i just wanted some other advice so when i go change my coils, and i still have the problem i know where to start looking next..

I am n/a but also f/i since i do spray. I will be turbo this summer hopefully if all goes well w/ my settlement.

and if you back off and just ease into the throttle you can maintain speed. then eventually it will die. (or that is going to start happening soon.)

much more likely fuel pump. it is weird. car runs fine for about an hour. then it is like the ignition cuts..

i have been through it more than once..

i'm with swoope on the fuel pump . I've had similar problems in other cars (not the 8) when fuel filter is blocked .
I would be almost positive it is NOT your coils but if you have lots of miles on them they should be replaced anyway

wassup_nuthin

Swoope so your saying quote "it is weird. car runs fine for about an hour. then it is like the ignition cuts" unquote. that you have had that exact same problem and it was your fuel pump. So would you have any idea why it was really bad w/ my mazport ignition then got better for a little bit w/ my oem ignition? But you are right it only seems to do this after its running awhile. oh and what you said about if you give it gas it will slow it down till it dies, thats what happend it texas when i broke down! but ide been driving for about 10 hours too.

where can i get a new fuel pump? say a walbro 255? i found stock ones ebay for abou 150, but ide rather just upgrade if i have to replace it.

ok, well i may order a fuel pump j/b i am sprayin nitrous rightn now and will be turbo soon so it will have to be upgraded any ways.. So where can i get a walbro 255 fuel pump at? im searching the net but cant seem to find one for the rx8

swoope might have some good info for you on that - there is a possibility the 09 pump will fit . Someone needs to try it ......

wassup_nuthin

what would be the advantages w/ the 09 pump fitting? wouldnt i be bette off w/ a walbro??

swoope

wow,

lots of odd questions..

first. dont mess with the spray till all is well..

a new pump is 120somthing shipped from onlinemazdaparts.com. and i would bet you a lot of money that is the only issue you have.

now what caused it is a different story..

wrong premix
dirty gas
water
bad juju

but really replace it with a stock pump..

simple story the internal sock gets clogged for what ever reason. pump overheats. car has issues. it gets worse with time.

search frankenpump.. we are still learning.

btw, it really is not the coils. if you turn the car off and let it cool it will start up and run fine for a while.. frustrating i know, i have a spare set of coils because of it..

beers

wassup_nuthin

well thank you very much for the info. Now I do not know why you would say I have alot of odd questions since I did not research about the 09 pump, and i was told to try that. but I guess ill do some research on the walbro pumps and what not. Now i am going to order a stock one, but is there a reason why i dont want something like a walbro, or mazport? My main reason for this is i will be going turbo this spring and i really dont want to replace fuel pumps twice, since i hear its a bitch in the rx8. well swoope thank you very much for all your info i really appreciate it!

dont recall you mileage.. but the pumps do go bad..

premix, and bad gas can have a big impact on that.

if this is just a daily driver, with no track time to be expected the stock pump is just fine..

if you need more info. please pm me..

as to the walbro nothing is a easy swap.. and sometimes less is more.

@!!narotordo

Any update on this issue?

dieselsdad

Maybe his "settlement" didn't go as planned?

i believe i read posts of him driving around after this, so i assume it was fixed.

and honestly dude, you go around bumping year old threads consistently asking for an update. why dont you just PM the guy?

my stock pump is going downhill

Getting P0171 lately, happens ONLY when the tank is 1/2 or less.

Full of fuel, no CEL.

I will 99% take the Walbro swap path. Will make a DIY with pictures

doubt it,

but se hablo pm?
