Just what it says

A misfire on cylinder #5

Don't use it until you have it resolved
You could damage the exhaust converter
or damage the engine if you continue to use it

SOURCE: My 96 honda accord is giving me three different

I would start with a full tune up. If it has never been done then that is the best way to start. Make sure that you gap your plugs. NGK plugs are the best for any and all Honda's. Let us know how it goes.

SOURCE: rough idle, dies when trying to give it gas

it'll either be your ignition system (spark plugs, distributor cap, etc) or more likely your fuel system (most likely your fuel pump or your fuel filter)

SOURCE: 1996 chevy 4.3 vortec multiple missfire p0300 i

Had this problem, had new crank sensor put in, new timing chain and gears. Before that though we did plugs wires, cap, rotor. DO NOT use advanced auto cheap stuff, USE ac delco. after that put a new motor with all of the above new again. Here it was the computer on the radiator overflow tank on the inner fender well. Someone has unscrewed it and it had condensation in it. These are 150 new but you have to have someone flash it in to the motor.

Van idles fine but when going the the road giving it gas it acts as if it isn't getting the proper gas ... it back fires....repleaced fuel filter and pump, crank and cam sensior

sounds like the timing is off. check the firing order to be sure your plug wires are on the correct positions on the coil packs. if that checks out, possibly a timing chain may need replaced. i hope this helps

Ford probe idle fluctuating

Sounds like you have bad gas. It can get strong mix of gas to give you the right idle, but when it has water mix, it will cause the car to fire like it should. This will then give you a low, rough, or just cutting off idle. Try mixing water remover in with the gas. You may have to drain the gas out or just drive it like it is until the tank is almost empty. Fill up with gas (from a different store) and you may want to change the plugs after the good gas is through the system. I'm not saying the plugs are bad, but there may be a lot of moisture beads from the water sitting causing rust.

2002 grand am 3400. # 5 cyl missfire

It sounds like the problem is isolated to that one cylider if that is the case you may want to check the compression on that cylinder if it is not electrical and no fuel problems it has to be lost of compression

You may need a new wiring harness. They have to be ordered from Germany. This is my guess. (I am having a similar issue with my '94; rough idle, #4 cylinder not firing intermittantly, replaced plugs and 8 ignition coils; new harness is my mechanics guess)

cheers and buena suerte

Number 1 cylinder misfire

No the only thing the san would show is a missfire, you need to test the injector and make sure it is getting fuel to the cylinder
