I am new at these codes, can someone help...........

[overthehill]

My '89 started running rough quite unexpectedly the other day. I got on the website and figured how to pull codes which I did but I'm not sure how to read them. Engine off i got 11 and 14. Engine on I got 12 and 25. Can I get some help here?

Thanks

Thanks for the response. I am a bit stumped by this problem. I've had the car since new and it has about 150K on it. It has run exceptionslly well until just the other day when it started misfiring under load and popping thru the the intake. Sounds like a lean condition to me but none of the codes I've come up with seem to address that. I've cleaned the MAF sensor and even replaced the IAT sensor. One thing I have discovered is that my CEL was not working at all. Nice to know!
