Cold misfire could be due to the following reasons:
- Ignition timing too late.
- Spark plugs gap too wide.
- Faulty spark plug wires or distributor assembly.
- Weak engine compression, or valve clearance too low.
- Leakage in the vacuum hose or intake manifold.
- PCV valve faulty.

SOURCE: my 2000 honda civic engine light on code p1456

Hey I had the same code and I have a 2000 honda civic lx. My cousin works at honda and drives a '96 honda civic and he has had that code before on his car as well.

First thing he came up with was that the catalytic converter was cracked. We checked mines, and lo and behold, that's what it was.

Look under your hood, and there should be a catalytic converter with a sensor sticking out of it. It is connected to the exhaust manifold and the sensor sticks out of the heat shield. Around the sensor, look for a crack. If there's a crack, that's your problem.

Random cylinder misfire

Scan the computer for trouble codes, unless that is where you got the random misfire code. It may point out the problem. Misfires are usually fuel/air, spark (ignition), or cylinder compression related. The pcm senses a loss of power through the crank sensor, noting the crankshaft doesn't turn as fast as it should. If it cannot isolate it to a particular cylinder, it will set the random misfire code.
Would be good to know what fuel pressure is as a start. Note that cold start problems may be fuel related, as the engine requires more fuel on a cold running engine. If the coolant temperature sensor is out of whack, the computer may not realize it is a cold engine. Just a possibility.

Misfires when cold

Just means it isn't warmed up yet when sputters and misfires. Most likely a bad connection on the temperature sending unit in the engine or that sending unit is faulty. This sending unit tells the computer when engine is warm or cold and has to be functional. When working properly, it tells the computer to put engine in cold start mode, which it is not doing. The sensor is stuck in open position or warm mode and not giving the engine enough fuel when cold making it misfire and sputter. Fix that and you'll have no other problems with revving either.

02 bmw 325i misfire cold start

plugs and wires. yes wires are the biggest issue with a misfiring engine. check the gap on the plugs. sometimes they are gapped to far and cause a cold misfire issue. simply pulling plugs and look at color of the insulator will tell the condition of the engine. normal should be a golden tan color darker means its to rich or burns oil white ask means to hot and should use a colder plug
