This is a problem I am getting now after this following thread I had posted:

I sent my injectors to rehab, injector-rehab ( http://injector-rehab.com/shop/RX8-a...ification.html ) and I got them back with excellent results, all of the secondary yellows are producing 800cc/min flow, and my primary reds are at 720 & 740cc/min.

Since I was having the Issues with my injector set up I had before I decided to roll back with the stock injectors with an upgrade. I installed them and now my 8 is running in limp mode with CEL code P0335, the essentric shaft sensor "A" malfunction producing codes.
Now I dont know if that is actually the cause, maybe my AP is masking codes. I am wondering why now that I changed my injectors I am receiving that code when I hadnt before its weird lol. So I took it out and it looks pretty clean, could see all the surface of it, but I decided to scrub and clean it up a bit anyways, and I am still having the issue. Followed up with the 20 brake pedal reset.

Here is another thing I am thinking, I had been driving ever since I have had the turbo installed with the issues I had been having from the link above, well there had been lots of back fires and I am wondering if my cat being TOAST would have my car running in limp mode? I havnt taken a look at my cat to see, but with my 8 shooting flames all the time im thinking it could be...

If its not one thing its another lol, thanks for any advice guys.
