My winter beater (91 acura integra RS) is acting real funny.

When I shift from park to reverse, the gear selector lights go out and will not let me select a gear.

So, I place it into park, and the gear light for P does not come on. I turn the engine off and then on, and still no P light. I wait a few seconds, and it comes back on.

My feeling is that there is a sensor that detects what gear is selected is going bad. Is there 1 sensor?

Also, in the past week, noticed it was difficult to take key out as it does not think that I'm in P and does not let me take out the key (even though the P is red).
