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!

 

I had the same problem with my ZC swap. The check engine light kept comming on with a code 1. I started using higher octane fuel (93 octane). After about 100 miles or so the engine ran smoother and the light never came back on.

 

I had the same code when I did my zc swap. I rewired and replaced my O2 sensor and that got rid of it for good.

 

Thanks for the suggestions so far. I probably replace the 02 sensor this week. Anyone else have other ideas on this problem?
