It's a 96 GSR in a 96 Civic. I passed the State Ref a year ago, they said I didn't have to smog until renewal came up. CEL came on for "Too lean" and "Misfire", initially changed my o2 sensors and spark plugs, using only Denso/NGK. Misfire went away, system too lean is here to stay. CEL came back.

Today I, checked for vacuum leaks, sprayed carb cleaner all around vacuum lines, motor had no changes. And I cleaned my MAP sensor. Need to pass emissions, but the CEL codes and the monitor says my stuff ain't ready. Also, erased all the codes- I'l let you guys know if it comes back. But shoot me ideas on what else to do, thanks!
