: I was getting on the freeway today and I was doing 55 in third gear. All of a sudden I lost power (about 5000 rpm) and the CHECK light in the instument cluster came on. I shifted into fourth and I regained power

First thing that comes to mind is the rubber air intake boot between the AFM and air plenum. Look for cracks. Second, check the fuel pressure. You might have a pump going bad and are running it out of gas at 5k rpm.
