2000 honda civic vp. engine started missing and skipping while driving check light engine came on , I changed plugs wires, engine runs smooth now, but check engine light remains on. Do I have to reset , if so how do I do it. thank you curdog29

misfires are from coils , plugs , HT leads , and injectors and fuel pressure . If the head got that hot then it is possible that the injectors have an internal problem that shows when they get hot and the electronics breaks down.

Usually you know when you need sparkplugs when it starts to miss. That is it runs smooth then kinda skips, runs smooth, then skips. Spark plugs will not cause your engine to cut off completly. Could be a coil problem or a fuel system problem. I would check fuel filter or fuel pump.

get the coil packs cecked as one could be sending to much juce to that plug also is the wire next to any heat sorses

Sounds like engine miss fire! Check to make sure your whole ignition unit is fine... examples....distributor, spark plugs, plug wires, ignition rotor, ignitoin coil...

p0325 is referring to the knock sensor. normally it's not the sensor itself but the wiring, connector, or the signal is missing. the sensor might be bad. here's a honda forum thread that discusses knock sensors.

I have a 2002 Honda Civic Ex, it has been over heating but only in stop and go traffic, never on the freeway, i have replaced, timing belt, water pump, cooling fan relay, cooling fan switch, flushed radiator. There is no white smoke coming from the tail pipe and the oil is clean, when the car gets hot i can smell the coolant pretty strong, car has never completly overheated gets about 3/4 of the way til red.

P0300 indicates that there is multiple miss fire in the ignition system. P0303 and p0304 indicates the miss fire is in cylinder #3 and #4. Replace the spark plug, and wire set, and rotor and cap if there is one. Can not remember if there are coil packs on the civic, the age thing. change the fuel filter and clean out the fuel injectors with fuel injector cleaner for the next 3 full ups. When the spark plugs are removed, inspect them for condition, if there clean or dirty with carbon build up. which would indicate how the engine is running. Keep me posted and drive safe.

Fuses nearly always blow because of a bad earth. The switch only needs to short for a moment and the fuse will blow.

See if you can find a replcement swtich from a local breaker's yard or ebay and go on from there.

changing the spark plug will not gonna change anything good in the system if i were you,you might check your idle air control valve if functioning right or check you wires goes to it their are possibilities that it might burned up or you might wanna pull out the idle air solenoid they usually tend to have carbon in it cleaning it may resolve the problem sometimes..

Before changing you pcm try cleaning your egr valve. remove the valve and see if its stuck in the open position if so use a small pick to clean around the spring.
