hey guys i'm new here, i've got a 1993 Honda Civic LX sedan. about a month ago my car started to loose performance and fuel mileage (went from around 28 in town to about 15) i've replaced injectors, plugs and wires. still nothing. i'm kinda getting a little frustrated with this because my Camaro is getting better mileage right now anybody have any ideas to what might be wrong?? (btw, the car doesn't have a Cat on it, factory one was removed before i bought the car)

 

is it running rich? can you smell it in the exhuast? it could smell a little worse due to the fact you do not have a cat, any cels? try checking the timing also.

 

it doesn't seem to be running rich. O2 sensor is factory stock, no check engine light, i haven't hooked it up to a code reader yet. i'll have to check in on that

 

i checked into it, hasn't thrown any codes. i'm really friggen confused on this right now...

 

check air filter, fuel filter? when was the last time they was changed?

 

well crap, it was the O2 sensor. replaced it yesterday and drove about 300 miles, only had to fill up once (started at half tank). it's back up to around 25mpg, still not the best but better than 15
