How do I fix a misfire on cylinder 2?
First make sure you determine the location of #2 cylinder.A misfire just means that the ECM has determined that that particular cylinder is slacking off, so to speak. It is not contributing. So your code would be a PO3O2.Next thing you should do is determine if you have spark to that cylinder and how strong the spark is in kV. You should have anywhere from 30 t0 50kV spitting from the coil.If you have spark, then you have to determine if it is going into the combustion chamber through the electrode of the spark plug. The spark plug could be "bleeding" the spark away due to a cracked insulator or moisture between the boot and the ceramic portion of the plug.If spark is not the issue then we get into the realm of more in depth diagnostics.Is your injector "spritzing"? Is it injecting too little or too much? Do you have a scan tool that can tell you when the misfire occurred and under what conditions, called a "freeze frame" parameter ? Very useful.Is the misfire occurring at idle or under load? What is the static compression like in that cylinder compared to the other ones. What is the running compression? Can you do a "leak down " test to determine the sealing of that cylinder ? Are you sure that intake runner to that cylinder does not have a vacuum leak?. Does your car have individual EGR passages for each cylinder? Are they blocked ? V6 Honda's have small channels for EGR and when they soot up it can send the diagnosis barking up the wrong tree.Most commonly misfires are caused by the lack of /or weak spark. But not always.
How much does it cost to fix a misfiring cylinder?
Ouch, spark plugs don't typically don't break. More often than not someone tries to remove it to check it and the carbon build-up on the exposed spark plug threads inside the combustion chamber are too gummed up and it seizes in the head, snapping off. Typically it's someone trying to check the plug that broke it. If the plug is broken off then it depends on how it's broken as to what repairs are needed, if it's seized in the head then you are going to want a professional to handle it else you're likely to end up with a damaged head. Once that problem is solved re-check the system, a missfire can be cause by a LOT of stuff... plugs/wires/injectors/compression loss/coil pack/etc, it's not like it was 40 years ago where plugs/wires/cap/rotor/condenser solved all.
How do you fix a cylinder that misfires?
First step would be to replace the coil wires and spark plugs,these go hand and hand no point in replacing one and not the other.These are the most common problem in having a missing cylinder.However if that does not work than diagnostics would be needed into determining if its either the coil pack/distributor, or the injector.As far as symptoms, you will get shaking when idling.This can be felt easier in a 4 cylinder than 6.You will also hear a noticeable ticking noise, which indicates a miss.Avoiding this, causes wasted fuel being sprayed into a non working cylinder, and potentially clogging your catalytic converter,in time.
How much does it cost to fix a misfiring cylinder?
You have the 5.4l which has an extended plug that does break off in the plug hole but can be removed with an extraction kit. This engine is famous for this problem. A dealer should be best equipped for the job as they must see thousands of them. The Labor to do this job is expensive and the plugs are a special design that are also a lot of money but not nearly as much as pulling the heads. I would expect a 500 dollar bill.
How long can a car be driven with a cylinder misfire?
Provided you've consigned this car to the junk yard, there's no reason to fix it. Go light on the gas and keep the RPM high (use "3" for your automatic trans) so the engine doesn't shake too badly under load. The trick is to use a light foot on the gas. Drive like grandpa.
Cylinder #4 is misfiring on my Ford Expedition?
I totally understand you concern because there are way too many wanna be certified prideful backyard greasemonkeys out there who think because they worked on one they worked on em all. Or they work in chop shop garages that require no codes. Anytime you hear " it COULD be THIS or it COULD be THAT"? Dude, RUN and go to an established dealership or garage and just pay the extra money because at least you know you are going to be getting the real deal and i don't know about you but my vehicle is like my baby. I have to say though, i agree with the guy at Auto Zone. Cylinder 4 is misfiring so you need a spark plug for cylinder four. Sometimes it really is that simple. All you need to decide next is how much you want to invest in a spark plug. I tend to invest in the nicer ones myself but if you do you might want to make sure it matches with the other ones you got so it might be time to change em all out while you are at it or at least check the others to make sure they are alright too.
I have two cylinders misfiring, can I still drive my car?
If the only indication you have is the check engine light and the engine is still strong and smooth, go ahead and drive. If the power is noticeably down and the engine is shaking, better not to. The codes that indicate specific cylinder misfires are P03xx, where the xx represents the cylinder that it says is misfiring - there will be one code for each accused cylinder. However, misfire codes are some of the most common false codes. All the computer knows is that the crankshaft is averaging slightly lower speed after the cylinder was supposed to fire - if it is slower the cylinder must not be firing regularly, right? Not necessarily. The first thing you will want to do is to reset the codes if you didn't when you read them. If they come back right away there may be something to them, but if they come back in after a while the computer's teasing you. If the light doesn't come back on right away, try fuel injector cleaner in the tank. If it has been a while since the last tune-up, now is the time. After these steps, reset the codes and see how it does. Because you didn't mention poor performance or rough running I think that will do it.
How long does it take to fix a misfire on mazda mpv cylinder 3?
I have a 2000 mazda mpv. The check engine light started flashing.I took to mechanic shop and was told it had codes P1518, and P0303. One is cylinder shutter valve stuck open and other is cylinder 3 misfire.How long should it take to fix this problem? The mechanic has had the Van for 2 weeks now? He says he replaced EGR valve and put some fuel injector cleaner addative. I need help,does anyone know what else I should do?
What does "misfire on cylinder 1" mean and how do you fix it?
not sure what engine we’re talking about or how this was determined , but assuming its spark-ignition (gas/petrol) type , then there are three main reasons for misfire . #1 low compression ; a valve leaking , head gasket leaking , or broken piston ring . #2 weak/intermittant ignition ; faulty spark plug , high resistance in plug leads , faulty coil , or faulty distributor if used . #3 wrong mixture ; faulty injector , vacuum leak . #1 problem can be verified by a compression test , #2 can be checked by interchanging plugs , wire and coil pack one at a time . #3 is a little more difficult , but injectors can also be interchanged , check vacuum hoses for cuts/holes or completely disconnected .
What are the effects of driving a car with a misfiring cylinder?
OK. I am a gear head who loves working on cars and has done so since the 1960’s.If a cylinder is misfiring because of an ignition problem you will, in the short term, just experience a loss of power increase your fuel consumption. In the longer term, continuing to drive it that way could destroy a coil and cost you more money.If, however, the misfire is caused by an injector problem, you could seriously damage your engine. Running that cylinder too lean will cause it to overheat and potentially damage the valve or the piston. If it is running excessively rich the unburned fuel could be washing the lubrication off of the cylinder walls leading to severe wear. In either case, repairing the damage will be expensive.NEVER drive a car that has a problem. NEVER drive a car in which the Check Engine light is on. If the Check Engine light begins to flash, SHUT OFF THE ENGINE, NOW! A problem that to you seems small, if not repaired, can cause a lot of damage that will be very expensive to fix.Read your car’s manual. Do exactly what it recommends. Find a mechanic you trust. Doing preventive maintenance will cost you a lot less than repairing the damage caused by neglecting to keep your car serviced.
