On her Facebook wall, FB Friend Jill Kuraitis of Boise writes: "My car wouldn't start. I opened the hood and peered around - might as well have been a bomb factory in there for all I know about cars - and waved my hand around. Let the hood slam and the car started. For a fee, I will come and peer at your car's engine too." I know how Jill feels. I'm a guy, and I'm clueless when something goes wrong under the hood. During my trip through Yosemite Park for a family wedding at Convict Lake (Mammoth Lakes area) in central California, my "check engine" light went on. We were miles from any help in any direction. Luckily, my brother Ed is a big-time mechanic & I had cell-phone service. He said not to worry. "Check engine" lights go on all the time. Usually something minor. He was right. I drove to the wedding and a thousand miles back home w/o problems.

Question: Do you know what to do when something goes wrong with your car engine?
