Okay so my tale of woo. Last week i was ripping the car through the canons when the car started miss firing and created sort of a shake to it pulled over ate lunch started it back up and drove.
Now when im driving hard and im around 9000k rpm the car will die for a few seconds and come alive again lost many corners to this.
Now for readers knowledge this is my first post and first rx8 im a virgin so go easy!
I replaced spark plugs
wires
air filter
coils
MaF is clean
now the car litterly takes 15 seconds to turn over feathering it lightly Cold and Hot
the car will finally turn over if i rev it up and let rpms drop fast car will die from 600-1200 Rpm is a rough and when it sits at idle its low and sounds like it wants to die.
My cat is gutted so no blockage (will dirty O2 sensors Cause this)
No check engine light yet
HEEELLLP ive spent hours on the threads and have done many diy stuff
Also i know about low compression but i dont want to rule anything out
The car has 105k maintained well

 

Fuel pump?

 

1st have you ever had your compression checked? not saying its the issue but wouldn't hurt to check at 105k miles

 

 

 

 

I am new to RX8 world and encountered intermittent stalling issues too. Did you figure out what was the problem?

 

welcome to the battle field i have a problem myself but i can offer some suggestions first any info on car miles? And how many miles you put on it (people will sell low comp... rx8s )
Second Battery Age
Codes?
Check dipstick for cream
unplug altittude sensor then test
spark plug age and wire and coils? Age
Clean Maf
Look up SSV Problems thats where im at now
Fuel Pump May be overheating how low is your gas?

 

Remember FUEL AIR SPARK

 

I have the older style ssv so im sure its carboned up also your ESS sensor could be cleaned if your engine is oily

 

some quick questions...

Ever replaced the O2 sensor? May have finished it off.

Fill the tank a little over half way. This will keep fuel pump cool. Then try it. Do not fill it if you want to take the pump out. If you are losing it in the corners, are they left hand corners? Left corner stumble = Fuel Pump can be issue with even half a tank of gas.

Get an ultragauge, track fuel trims, specifically STFT, but LTFT as well. Is the car desperately trying to add fuel when it dies?

This data will help.

 

 

I would check and reconnect the MAF sensor. Any trouble codes?

 

Actually 0.01 pounds is about right. The normal idle MAF reading for me is about 5 grams which is about 0.01 pounds.

 

My bad, did not do the grams to pounds thing.
