About 3 times in the last 2 months my check engine has come on. I did the key trick to try to get a code, but after the 111111111-9999999999 deal the car doesn't show any code, it just goes right to the mileage as if you had turned the car on normally.

Can anyone help me out? I'd either like to know what the code is, or why it's giving me a check engine light. The first two times it happened, nothing appeared wrong with the car. The 3rd time (today) the car downshifted by itself and wouldn't go back into 4th gear.

I'd bring it to a place like Autozone where they check it for free.

On a 97 that key trick won't work. You have to do this one:

The "Key Tricks"
Older (OBDI) models - Start with the ignition off. Within five seconds, switch the key on, off, on, off, on. ("On" is NOT "Start" and "Off" is NOT "Lock"). The "check engine" light will flash. Count the flashes. Each code is a two digit code, so a (for example) 23 would be FLASH FLASH (pause) FLASH FLASH FLASH (long pause). It will never flash more than 9 times, so watch for those pauses!

I tried the same one you tried a long time ago and it did the same thing so I tried this one and it worked.
