i have a 92 civic cx, the problem-- when i accelerate normally or harder the motor bogs and misses, if i press the pedal down gradually then it remains running smoothly it just takes too long to increase speed for highway driving and makes driving with the a/c almost impossible. i am able to drive smoothly on the highway once i am able to maintain a constant speed. i have no check engine lights and my oil and coolant look ok. so where should i start? O2 sensor? MAP? i don't know, and i don't just want to start replacing everything as this is my daily driver/ beater. thank you for your help.

 

check the gap on the spark plugs and clean them up.

 

Are you throwing codes, if so, retrieve them to start off, see what the ECU thinks is screwing up. A high load miss can be caused by excess air gap in the cap/rotor assembly, the plugs, and excessive resistance in the primary coil circuit, preventing a full spark charge. Check the maintainence items first, and your codes, and then post.

 

throttle valve?
injectors maybe? you might be running too rich. :[

gl with that
