bump

 

if there are any mistakes in thses codes let me know, i'll try to fix it

 

Does anyone know if p0030 will cause limp mode??

 

that is your primary o2... so i would assume yes

 

Never knew about this thread since now. Thanks for sharing.

 

You should start your own thread 'Things Monchie Doesn't Know"

...be a long one.

 

^^^ +1 on that ^^^

 

Repost but thanks for sharing for the noobs and search-lazy

 

Hi I own an 04 auto rx8 with 115xxx miles. Every thing is pretty much stock, I have changed the coils, plugs, and wires. Replaced the fuel pump and new starter and checked the compression and it hits 120-150 psi. My problem is the car idles pretty rough and stalls at idle and whenever i put it in gear. Also whenever it doesn't stall out, the car is really rough while in gear like the car rpms drop and the ecu i guess tries to keep it from stalling and has the needle jumping up and down and has my car shaking and jumping. When i press the gas down it doesn't accelerate normal i have to press and fiddle with the gas peddle constantly for it to actually raise the rpms up and semi drivable but as soon as I hit the brakes while driving like a stop sign or light, it does the same thing and i have to repeat fiddling with the gas in order to raise the rpms up to speed. The car is just sluggish and rough. I have a solid cel light and the codes were P0743, P0171, and P0506. I need help trying to figure out what the problem is. I have cleaned the MAF sensor and have new coils installed and checked my plugs and they were still pretty new. Only thing I haven't checked is my cat converter. It doesn't show any signs of it going bad like glowing red or anything so i'm going to check if its clogged but besides that I have no clue what else it can be. Please someone help.

 

Sounds like an air leak in the intake.

Clean the MAF sensor (properly)

Check for cracks/loose intake piping.

Check all hoses that link into intake, especially the one from the oil filler to the tract.

Somewhere you have excess/unmetered air getting in.....


.

 

Could be a throttle body issue as well......

 

dose anyone know what these codes mean....from mazda rx8 2004..
UO 101
UO 155
UO 100
UO 101
UO 100
its showing these 6 problems

 

"U" codes are generally thrown by the Canbus communication network.

These codes are for comm failure to both the PCM (computer) and the TCM (transmission).

First is always - check the battery terminals and charge.

If you haven't touched any wiring or had an accident, you can focus on bad grounds and corroded terminals at the computer connector.
The main ground for the computer is right behind it, under the barometric sensor.

Good Luck....

 

it’s pretty simple; 18 years later after the RX8 first came on the scene, pretty much everything you need or could ever want is already here on this forum if you’ll just make some effort on your own behalf. In this case, right at the very top of this same forum area page in the Stickies Section:

https://www.rx8club.com/series-i-tec...n-guide-26291/

but to your credit at least you didn’t go full Lil’ Billy and start a new thread, so I’ll give a “thanks” and there’s the link for you.

 

I have a P2259 ( Secondary air injection system control 'B' Circuit Low)
how to fix it? plz
