2007 WRX, 160xxx km, no parts mods just a tune. I've been dealing with this for a while, although I've been somewhat lazy about it because it happened right before the winter hit and my garage isn't heated... I had the codes come up for the secondary air system (don't recall which ones) so instead of going to the dealer about it I had a tune done by a local guy with a great rep. Bumped me up to 200whp, and deleted all related codes while he was tuning. I have not yet removed the system but i have disconnected the wiring harness to the pump. Awesome, until my cruise light came on without a CEL.
Cruise light now flashes almost daily, feels like my car is a little limpy, and will not throw a code for diagnosis at all. Cruise light flashing goes away if the engine is shut off for a few seconds and then restarted. I'm at a loss here so if you have any thoughts, I'm all ears. Thanks.
