i just put my ams intake and had my ams turbo back exhaust with high flow cat on. had the car a few days and on the way home on the interstate at 60mph the service engine soon light came on. anyone have any idea why?
Could be the high-flow cat, too. Interfering with the O2 sensor. Instead of trying to diagnosis it outright, why not go get the code pulled at Autozone or something? People will be able to give more specific advice that way.
did you get tuned? AMS intake's maf housing is larger than stock. running it without a tune means your car has no idea wtf is going on and is wrong about everything
