I also have an 88 civic 1.5 STD hb.
And maybe it could be related to the injector thing. When I race, it is
amazing how fast it consumes the gas. I mean in a quarter run, maybe half
gallon. You can see the needle drop after you are done. Since I have the car
it has behaving like this, it only has an intake and 100 k miles. It runs
good, or as good as it can run. Any ideas?
