Chances are that you have a bad plug wire
might be a misfire in a cylinder...
What's wrong with my 2003 Chevy Cavalier if the check engine lights on and a friends computer said "misfire cylinder 4 "? It studders also. thanks Dawn
In any car, if you have a specific cylinder misfire, check the spark plug, spark plug wire, fuel injector, and compression. The computer could also have a problem. You will need to consult the detailed manufacturer's diagnostic chart for that, but the basics remain the same.
I had the same problem and went ahead and replaced cylinder 1 coil and all the spark plugs and it worked.
A misfire on cylinder 3 in a 1996 Blazer can be caused by a faulty spark plug, fuel injector, or ignition coil specific to that cylinder. It is recommended to perform a compression test to rule out any internal engine issues and also check for vacuum leaks. Additionally, scan the vehicle's computer for any trouble codes that could pinpoint the exact cause of the misfire.
First things to look at are your distributor cap and rotor, spark plug for that cylinder, and the spark plug wire to that cylinder. If you can't see anything physically wrong with any of those, try switching the spark plug with one from another cylinder, if the misfire moves to the new cylinder, you'll know the plug is bad. If it wasn't the plug, try switching the plug wire with another of the same or similar length, again, if the misfire moves to the new cylinder, you'll know the wire is bad. If that doesn't help, ask "What could cause misfire?" in the Ask box above or click on the link below to that question and answer. There is a lot of information about misfires there.
If your check engine light is flashing an engine cylinder misfire has been detected
This is usually a bad coil pack. This cylinder is located in the middle back. I had a lot of dealers that didn't know and some manuals are wrong. They run 1,3,5 on the back.
Weak ignition coil? valve (intake) hanging up at times not allowing fuel mixture to enter combustion chamber?
It depends on what caused the misfire, and it depends on what you mean. If you are having constant misfires, then there is either something wrong with your ammo, or there is something wrong with the pistol. If you mean what is the proper procedure for clearing a misfire, then you keep the gun pointed in a safe direction and rack the slide to eject the bad round, or open the cylinder and eject it if it is a revolver.
Sounds like you ave a misfire. Could be as simple as needing a tune-up.
