Alright guys, i have an obd1 h22a1 in my accord right now...its running fine but throwing 2 codes. Its throwing code 1 and 43 which is the O2 code (cuz my sensor isn't bunged yet) and a Fuel Supply system code.

My question is, what can cause code 43 to come on and how did you guys fix it?

 

So you don't have a bung in the exhaust yet & the O2 sensor is either dangling or it's not installed? That would probably cause both those codes.
