Well my checknegine light came on and my speedo stopped working. I have a cobb port so i'm able to reset the ecu and clear the code but the speedo is still on the fritz and he check engine light comes back on shortly after. It also seems that the rev. limiter is set to 4 1/2 grand while the check engine light is on. Is that normal, i'm guessing its just a saftey. Any help would be great on how to fix this thing....oh yeh, its an 05 wrx wagon.
