I've been searching through this forum, as well as swedespeed.com, but maybe someone here can offer some help?

While driving, my "Brake Failure..." light came on, along with another short message after it, though I didn't get a chance to see. And soon after, the "Check Engine" light came on too. I pulled over, shut my car off, and restarted, which resolved the Brake Failure light (for now, anyway), but the Check Engine remained on. Also, I noticed the feel of the car wasn't the same-- when I would push the gas, it wouldn't go as quickly, or power up like before. Also, when I shifted, it felt knotty and the car kinda shuddered. Any idea what could be up?

 

Sorry no idea without you giving us codes to go from. Try to have the codes pulled.
