Same as the post on the old board.

91 Civic W/a D16a6.

Code 1: Oxygen content.

Getting a code 1, and in extreme city driving when there's no air gettin on the engine she idles at 2000 rpm... I can pull out on the gas pedal and it stops...Until it's depressed again. Doesn't happen on the highway or just regular driving.

I put in a different (not new) o2 sensor, I KNOW one of them is good but still the same thing.
All my grounds have been checked. The throttle linkage is ok, No vacume leaks.

ANY ideas?... I wanna get this beaotch figured out.
