hey guys my civic is running really bad latly it hasnt been drivin since march exept around the block maybe once a month anyways now from 1k-3k rpm it will bog extreamly bad then once you hit 3k it just goes fine is this something a bad o2 sensor would cause......

and also i need a new lower ball joint does anyone know how hard it is to remove and install i have heard its a pain the a$$ but im just wondering what you guys think

 

Maybe a new clutch

 

Usually, the check engine light will come on when your O2 sensor goes bad although not always the case. O2 sensor also does not work when the engine is cold.

 

ive got the same problem with my 92 lx. its an automatic... I replaced the o2 sensor and it didnt change it. i cant figure out what it is for the life of me
