Your piston ring is bad letting oil get threw and causing the plug not to spark.

Testimonial: "But my compression numbers were Cylinder 1 Dry 125 Wet 135 cylinder 2 Dry 130 wet 135 Cylinder 3 Dry 130 wet 145 cylinder 4 Dry 140 wet 145 so I don;t see how that's a piston ring when my compression is average."

    Is it possible that my distributor is not at the right setting? I did a timing belt change and the car is set at 15, but I didn't set the ignition timing. Another guy did it and he mioved the distributor. Is it possible he's wrong on the distributor? I think he set it like at 800, or 900 but I'm pretty sure a honda civic 93 ex is around 640 or 700 or so.

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

SOURCE: Motor Oil leaks from 1999 Honda Civic EX

make sure they are tight
could be time for head gaskets
make sure the old gasket from the old filter came off the block sometimes they come off old filter and stick this causes a leak due to improper seal.

I have a 2001 civic ex after it warms up the idle drops and it has a misfire on the #2 cylinder


Knowing the mileage would be helpful. Change spark plugs and plug wires. Also change fuel filter and air filter if they haven't been changed recently. If it still has a miss then run a compression test. Could be a leaky fuel injector also.

My honda civic lost power and there is oil on the spark plugs what is the proble and how do i fix it


If your plugs are oil fouled, then either the spark is weak and not firing correctly in each cylinder (you would probably have misfire) Or the 02 sensors are bad and the engine is running really rich.

Car wont start


are you getting any spark on the #1 cylinder?

97 Honda Civic shakes at start and check eng light comes on.


It looks like misfiring in one cylinder. That is why check engine come on. Misfiring can be due to spark plugs/wiring/worn distributor cap. Maybe also vaccum leak and clogged injectors (use injector cleaner).
You can read the trouble codes at Autozone store for free
