Here's the situation...

I've got a ZC with a 89 integra ecu. I cleaned my engine bay and covered certain parts (battery, intake, alternator, distributor) to prevent them from getting wet. After I was done cleaning, I started up the engine and my A/F gauge was reading extremely lean. After about minute or two, my check engine light came on and my ecu was throwing a 1 code. I reset my ecu, but the same thing occurs.

Can anybody help? Does anyone know where I can get the engine codes for a 89 'teg ecu? Did I fry my O2 sensor? Any suggestions are greatly appreciated!

Thanks everyone!
