We've had this issue before, our stove is about 12 years old. The bake ignitor starts to take longer to light, and there is an unpleasant odor until it gets going. Creepy. The replacement was pretty easy, remove the bottom floor of the oven, pull out the bottom drawer, and replace the igniter. It maybe a 20-minute job. My husband does it but I could probably take care of it in a pinch. The replacement part was correct and arrived on time. We had a fresh ignitor for Thanksgiving!
