Well my o2 sensor wire broke off, a machanic re wired it but some wires are left hanging because he doesnt know where they go. But it works becuase my car doesnt have a surging idle no more. Now when i shift gears into 2nd it sounds like im riding the clutch when my foot isnt on it.Now my rpms bog at 2500 after he re wired the sensor like it goes up and down really fast and the car jerks violently. The codes i got where

o2 sensor (i dont know why, it was re wired and it fixed my idle mabey its not wired proper?)
electronic air control- I know this is the ivac or something what can i do to fix it?

electronic load dector- I have no idea what this is.
Any help would be appreaciated. Thanks

 

can you post the actual codes #'s please? I might be able to look it up
