See if that allows your ecu to recalibrate system. You'll need to reinitialise power functions such as windows. Consult manual for this, it's easy.

I reread your original post and it sounds like you have a vacuum leak somewhere. Start by really checking under hood for loose connections on hoses, air filter box, and surrounding areas. Next, search Google for videos and info about how to test for vacuum leaks. Good repair shops will use a smoke system that introduces smoke into the system and leaks will show smoke departing where it shouldn't. You can do this yourself by spraying soapy water around and on intake parts and look for bubbles.

Near the back of your owners manual there is a picture guide of all the fuses and their locations. That fuse is likely in the engine bay fuse box, if not then driver side lower dash compartment. Each fuse compartment also has a diagram on the lid for fuse locations. Once you identify where it is, use the provided fuse puller or needle nose pliers to remove the fuse. Make sure car and ignition is off first. The fuse will have a metal element visible through its transparent body that needs to be solid throughout, if it's popped, you will see a break in the metal element. Which would be a good thing in your case:easiest fix. Then go buy another fuse of same amperage and replace.
