Angry Help please!!! CEL and 4k redline
If i press the gas a little before half way the car will redline at 4k and backfire like crazyyy right after eachother nonstop. Then the CEL light starts flashing. I did a CEL test and it kept saying "several rotors misfiring" could it have to do with spark plugs? I also feel loss of power like the engine is struggling to push the air out.
Also the car heats up alot.

Mods on the car:
CAI
cut off cat/resonator.
Stock catback is on.

I keep thinking its because I need to free more air. If i put on my stock intake it's alright.

well, if it runs fine with the stock intake, then the aftermarket is the problem. if the issue persists with the stock, proceed with coils, spark plugs, and wires....although at that mileage, I would swap them out anyways

The position of the MAF sensor (and the ID of the intake tube) is important.
Can't just throw anything on there and expect it to run unless it was designed for the RX8.

Damn it... my work has the pics filtered.

Now I have to anxiously wait until I get home to see it.

actually the maf may be fine, i guess that's the way it is on the aem
the piping looks too small tho, but it's kind of hard to tell from the pic what size
do you know the ID of it?
