I have a 92 civic lx 4 door and i am having troubles with it......it has slow starts and bogs down and almost dies when i try to accelerate and it has died on me once and in morning it takes 10 aseconds before it runs a smooth but very low idle.....it startes to run good around 4000 rpms what could be wrong..........?

 

Could be in the wrong forum ?

 

Possibly an O2 sensor problem....
