CODE #1 O2 Sensor CEL ???
 

Ok so I just got my b18c1 running again and only thing wrong is that I'm throwing a CEL code 1 for my O2 sensor, I'm running it with just headers and no exhaust cause of none to hook up, my question is: by having no exhaust would this cause my o2 sensor to throw a code due to incorrect air/fuel mixture and cause idle to be bumpy once and awhile?? I've also checked all the wiring and every thing seems to be in order, but I could be wrong, I'm running a Denso 4 wire sensor which I lost the coding chart for. Thanx you guys.
