I have a1993 Honda Accord Lx.
My idle does not stay stable. It jumps up to +-1000rpm. Also After I drive or it sits idling for a while the rpms drop slowly and eventually the car dies. Check engine light says that It's an oxygen sensor, but I bought/put a brand new bosch oem replacement. Disconnected the battery terminal and reconnected them again and let it sit for a bit - same story.... Also I replaced the gasket after throttle body and cleaned everyhting thourghly. What's wrong with it and how do i fix it? Top 3 black skinny vacuum hoses seem to be fine...

Thanks,
