Developed an engine miss - worse at low speeds - engine management light came on - pluuged it in - said miss-fire on pots 2 & 4 - cleared engine light and changed coil packs on pots 2 & 4 (off a spare engine I have)seemed ok but now the miss has returned although the engine light has not yet came on again - any ideas?
Try changing the spark plugs

I assume you mean low idle speed 500 rpm. Genarally a tapping noise comes from the valve train, and a knocking noise comes from the crankshaft connecting rods. The way that a mechanic will narrow it down is to use a mechanics stethoscope. You can get one pretty cheaply at an auto parts store. Put the metal end of the scope on a part of the engine and listen for noise. On the other hand, if your car is idling at 5000 rpm, it would also be making ALOT of noise.

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.
SOURCE: Squeak from front left wheel...
Can you describe the squeak?
Does it happen more when you turn a certain direction?
Try just pushing down on the front left of your car and let it bounce up and down, does it squeak?
I would say its probably mounts, there are usually rubber stoppers on shocks, mounts, well just about everything in suspension has a rubber bushing or stopper to reduce noise and rattling, they may squeak from time to time.
Check your shock absorbers for leaks, look for loose bolts on the suspension and steering components. If you think it may be a rubber bushing, you can get a can of dressing for belt squeals and spray down the bushings, this will eliminate the bushings being the problem.
If it is constant, all the time, whenever you drive it. It could be a fan belt or a timing belt (if the front of your engine is on the left side [assuming you have a transversely mounted engine / front wheel drive])
Check the tension on the belt maybe it is loose.
Hope this is helpful to you.

yes, this is the case of a failed throttle body, in which case it needs replaced, the car is getting too much fuel causing the high idle. this needs replaced asap. you could proably find a small independant honda shop that could do the work for less.
