Lately, my '91 crx with a zc has been bogging at low rpms in 2nd and 3rd gear (done it in all gears, but notice it mostly in these two). Its probably because 4th and 5th gears are usually only used for higher rpms.

Regardless, it seems like there is not enough fuel or something, thats what I suspected at first. The car threw a code indicating the O2 sensor might be at fault. I have bought a new O2 sensor and fuel filter and am intending on replacing these. Things I have replaced with brand new parts in the past 1/1.5 year include:
- starter
- alternator & belt
- plug wires
- all grounds redone
- main relay
- distributor cap, rotor, and ignition coil

I suspect that the O2 sensor is my problem, but I guess I am just looking for reassurance, and if there might be anything else that might be at fault. Any insight would be appreciated, thanks.
