91 integra - check engine light and sputtering

The check engine light on my '91 Integra is on. The car is still running, but it's running a little rough and it starts to sputter when the rpm's get high in each gear.

Any ideas out there? I don't know much about engines and I'm short on cash (that's why I drive a car with 220,000 miles on it!). Thanks!

Go to autozone, they will check the codes for free so that you can know what the problem is. It could be a O2 sensor, fuel filter, when was the last time you changed your spark plugs?
