My 1991 Honda Accord Ex is stuck in sport mode. It is an automatic with a button on the side of drive selector for "sport" mode which increases the rpm's by 1000 to 1500. A week ago my car started to randomly go in and out of sport mode regardless if the button was depressed or not. Now, for 2 days the car has been stuck in sport mode with the rpm's racing around 4500 when doing 55-60 mph. I check for a fuse, both under the hood and inside with no luck. I have no money to send it to the shop. Is this something I can fix at home? How? Help!

The sport switch sends a ground signal to the transmission computer to tell the computer you want power and the transmission/engine RPMs are higher. The sport switch at the shift lever has a red and a black wire going to it. Black is ground turn the switch on and off and see with an Ohm meter if the switch makes and breaks continuity or is the switch or wiring shorted. The switch appears to be naturally opened in the wiring diagram so it seems that with the switch "off" the red wire should have no continuity to ground.
