I don't have it, just a resonated middle pipe.

One more thing:
Yesterday it was heavy rain, immediately after I hit it - the car almost died. Rpms was jumping up and down, acceleration didnt exist (still in safety mode - 4K rpms limit). Guuuuuys I know there is someone who knows the answer

New info:

i've changed plugs and wires and the problem didnt gone. I also checked rear oxygen sensor - i disconected it and there was no diffrence? What does it mean - is it broken or maybe the front one is broken?

Many of us could tell you if we were there but diagnosing from afar is rather difficult. I am assuming coils have already been discussed.

have you try cleaning the throttle body?

Coils are new, throttle bpdy is clean (ive cleaned this when i was changing cai).

One more thing:
when I cam thru water, car almost died...
Sound is horrible, like a cheap car from 80's
And the car is whole shaking

Anyone one know something? Oxygen sensor what is doing when is broken? I recently unpluged it the rear one and there was no difference.

Im using now train to work, not a car anymore ;(

Maf checked

any update mate? i'm not expert at this.. but i would try changing the stock intake first and see how it goes.. i'm not saying you got prob with the Mazdasepeed CAI,but why not try it

Jax_RX8

Here is your problem - the combination of the intake, no cat, and exhaust is causing a too lean combustion - which throws the car into limp mode.

The cause could be one of several possibilities:

- THe ECU takes time to richen the fuel mixture after any change, but if you have not changed anything recently, it may have reached it's limit on how much it can richen the mixture.

- Vacuum or Intake leak somewhere can let excess air into the intake and lean the burn without the ECU knowing and being able to adjust

- O2 sensor clogged, failed, or not reading properly - causing ECU to not set fuel setting properly

Check these out and see if they help

sorry, but an open intake and open exhaust will not result in the engine running lean

stop throwing parts at it and playing the guessing games, take it to somebody who can check things like engine compression, fuel pressure, etc.

I've never had a stalling or running issue after resetting any of the memories; PCM, eccentric profile, etc. and have done so at least a hundred times, this is BS

I just got a report back, from the dealer, about a stalling problem I've been having. They say there is too much alcohol in the gas. This gas was purchased from the same station that put sediment & water in the tank and required the replacement of the fuel pump.
You may want to have your fuel checked.

If the car is hot and I pull the battery and reconnect, it will stall on the first start without fail, everytime. If I do it cold, no problems. It does take a 1-2 drive cycles to restore a 100% proper idle on my car. It does happen and is not BS. I can provide demostrations of this if anyone would like to see it firsthand. On an additional note, those in our club with stock intakes do not suffer this much if at all.

I went to service... they checked in the computer and there were two screens of oxygen sensors, for 2 of them. One was alive (just like a heartbeat in E.R. ) but second was straight line, So the solution was easy - oxygen sensor is dead. Ive change it for a new one! And its still the same . Remember that the cas in rain got a lot of problems to run....

ramzesgd

ITS FIXED!!!!!!!!!!!!!!!!!!!!!!

Not plugs, not coils, not wires and not the oxygen sensor!!!!!

Bloody MS INTAKE !!!!! I dun know how but my engine was going crazy with this!! Ive fixed from long arm to short arm and now its ok!!

whitebeau

nice.. wonder if the longer tube caused excessive vibration causing the MAF to error, but no MAF CEL's?

Is there a bracket to brace the main tube of the MS Intake?
