Question about 1996 Honda Civic

2 Answers

My car will stall when stopping. I have found oil in the air filter compartment, and the car runs well otherwise. In other cars I have owned this was fixed by replacing the PCV valve, yet I was unable to find this valve along the line from the valve cover to the air filter. Any thoughts? Thank you.

    Basically, this is not going to be a cheap fix then.

Yes, this vehicle is equipped with a PCV valve!

It is located underneath the intake manifold, slightly above the oil filter.

Although difficult to see, if you look from the driver's side through an opening under the intake manifold, you'll see a sensor. Look to the left of the sensor and slightly below for your PCV valve.

It is a little elbow with a clamp and may be covered in oil.

Your patience and dexterity will be tried, however you can replace it yourself.

Please let me know if I may assist further.

Testimonial: "Thanks for the input. I appreciate it. Do you think that replacing the PCV valve could rectify the situation, or am I looking at a costly repair bill? As I said the car otherwise runs well, just not after it warms up. It is a 1996 Honda Accord with 140,000 miles on it, and has not had any engine problems prior to this."

    Hello scuzlbut1 , replacing the PCV valve certainly will not hurt. If the crankcase is not ventilating, the result will be an increase in moisture and hydrocarbon buildup within the crankcase and oil. Keep in mind that the PCV system "vents" at or near the air filter and may give the appearance of oil buildup. Get the valve replaced.

    Regarding stalling: Check for any air leaks (broken vacuum hoses and other connections).

    As I said, the car is running fine. There is no sign of compression issues, rough idle or hesitation when accelerating (sp)n or is there any sounds coming from the engine such as a 'sticky lifter.'
    As you come to a stop, the engine will die. I am hoping that it is not the heads (there is no water in the oit, and there is no oil on the outside of the engine block which would show signs of leaking from the valve cover).
    This is my wife's car, and I am not very experienced with newer model cars, so I figured that the PCV valve may be worth a shot as I once had a similar problem with an old Mustang. The difference was that the PCV valve was located at the air filter where the line connects with the valve cover.
    Thanks for your time, and hopefully replacing this will fix the problem.

    Another potential cause for stalling: Your idle air control valve may also need adjusting or need to be replaced due to the idle air passage being blocked by a little carbon build-up. If build-up is the problem, a good removal and cleaning will do the trick or an off the shelf spray cleaner may get the job done as well.

    Give it all a shot and keep us informed!

    Best regards,

    I am still having trouble locating the PCV valve. I have checked near the oil filter, but am still not able to locate it.

    Again, I am somewhat unfamiliar with this car, so any other info you can provide would be great. Thank you for your time.

    Additionally, I spoke with a friend about the idle air control valve, and the symptoms don't quite sound like this could be the issue. Would the car want to stall even at an idle? I am able to start the car, put it in gear, and the car runs smoothly. The only time it stalls is when I am slowing to a stop, or slowing to round a corner. After the stall, the car will start and run like nothing is wrong until I slow to a stop once again.

    Thanks again, and I apologize for my ignorance concerning Hondas.

    Perhaps this picture will help. Notice the fitting that the oil filter screws onto. Since the Oil filter is removed, it is easier to see the PCV valve. Again, not much to see there except the connecting hose. It is much easier to see from under the vehicle with the oil filter removed.

    Yes, the Idle Air Bypass will cause similar issues, however you should get the PCV valve taken care of first. Also take you car to Autozone or similar and have them read the fault codes. This is a free service. Jot them all down and let us know what you find.

PCV valves have been eliminated in newer cars these days. They use a small restrictor instead. Usually oil inside the air cleaner if caused from a bad valve in the head cylinder

Volvo 960 wagon stall

if it is lacking power and stalls at stops, it may be a bad fuel filter. when car is off, the dirt inside the filter drops to the bottom. but as soon as its started it rises up. that is what usually causes a car to stall. when stopped. if the car bogs down on hills and it was fine before, then its the fuel filter. there are many things to make a car stall at stops, but check the fuel filter first then go from there if problem still exists. and check all vacuum lines in engine compartment. there may be a leak. clean throttle body out if needed. good-day! check and or replace the Idle air control. (IAC) it may be sticking.

Try cleaning the throttle body and butterfly plate. If that doesnt work, replace the IAC (idle air control) motor.

Stalls when stopped at a light

Do you have more information? Such as, does it do this every single time you are stopped? Does it ever happen when you aren't quite at a complete stop? How soon does it stall after stopping at the light (right when it's completely stopped? As you apply the gas to move again?)?

Mainly a vehicle will stall do to a problem relating to the fuel/air system. Specifying any 'special conditions' (very hot, very cold, etc.) when the stalling seems to be more prone to happening (if any) will help with a diagnosis.

It could possibly be a bad/faulty fuel pump, where the engine isn't getting the proper flow of gas (in a case like yours, it would most likely be an intermittent flow).

Also, a faulty throttle positioning sensor (TPS) could be the problem. These are a somewhat 'run of the mill' problem in vehicles in general and aren't overly expensive to replace. This is even more likely the problem if your vehicle stalls when you are taking off from the stop light. This isn't difficult to test yourself and there was plenty of directions to do so online and elsewhere.

A vacuum leak is another possibility. Another symptom of this can be a high idle (higher than usual for your vehicle at least).

Lastly, I wouldn't imagine this to be very common but it's worth a look, and i only mention it because it was the problem with my '87 Celebrity that suddenly stalled at a stop light, then kept stalling whenever i pressed the gas to move. The car had a known engine oil leak, one area of which it effected being the air filter housing (old-fashioned circular one). I noticed, once i finally got moving (albeit only for a short time before stalling again) it sounded as though the engine wasn't getting enough air. Even though i had just recently replaced the air filter, i checked it and found it was completely covered with dirty engine oil. I took out the dirty air filter and it solved it. It just hadn't been letting enough air through. So, simple solution though not commonly the case. No harm in checking anyways.

Good luck.

sounds like EGR valve and sensor this controls idle speed when at a stop. the po171 is a burn lean or rich code need to know what bank 1 or 2. also check for a vacuum leak from one of the hoses.

Oil in carburator in a 4 cylinder motor

Check pcv valve and vacuum hose to make sure they are working. Chances are that you have a broken or worn ring, or worn engine bearings. (excessive blowby) In which case there's not much short of rebuild or replacement of engine that will cure problem. You could remove the hose that is bringing the oil into the air intake off the air cleaner and route a longer hose into a can or something temporarily but it's not a cure.
