I have a 91 honda civic and my check engine light is on

Question

It has been on for about 4 months now and its to old to have it hooked up to a tester but the light under the carpet on the passenger side is reading code 8 and 1 does anyone know anything about that? The distributor cap, rotor and button and plugs are new, and it took away half the codes that it was flashing, it also bogs out but i cant tell at what RPMs because i dont have the thing on my car, and it sucks gas HELP PLEASE!!

Answer 1

It sounds like you might need a new oxygen sensor and/or fuel filter. A bad oxygen sensor will make the car run too rich, which kills your gas mileage. A clogged fuel filter will cause your car to have to struggle to get gas to the cylinders, which will also cause it to run too rich.

Answer 2

have you changed the oil lately?

Answer 3

i dont know how to answer your question, but amco is checking cars free for people who have check engine light on.they check mine and told me what was wrong for free.

Answer 4

Could be any thing i have a 2000 honda civic. could be a  o2 sensor a bad one can make your car stall.

96 and up cars have an OBD so you can check a check engine light she has a 91.

Answer 5

check http://www.geocities.com/chipman_13/ecu....

lights 8 and 1 would be code 9 and according to the chart that is a fault in the cam position sensor. This sensor is used to time the ignition and if it read wrong you will get the problems you described, The url above lists some common causes for the code.

Answer 6

prbally an o2 sensor.  a 91 model shoud have a diagnostic port under the hood somewhere(toyotas do) that you can jump out and it will flash codes for you, that you can call a honda dearlership, or check on line, which will tell you what the problem is.  on toyotas, the check engine light will flash the codes with a pause between, then a long pause.  for instance, 2 flashes, pause, 3 flashes, long pause,  would be a code 23.
