It sounds like you got a vacuum leak. Take a can of brake clean and spray it around the intake seals and watch your fuel trims to see if they go nuts. If there is a leak the engine might stumble when you find the leak with the brake clean. If it stumbles or the fuel trims go wacky, then you'll know you have a vacuum leak.
