Try retracing your steps. Check everywhere you were touching things, perhaps you accidentally knocked a vacuum hose loose. If the plugs can be adjusted, make sure they're gapped properly. If you have a voltmeter i'd check the resistance of the plug wires to make sure they're ok. Acceptable resistance of the plug wires vary from car to car. But obviously, the lower the better. It may be possible that you got the firing order wrong when you hooked up the wires, here is a site that will give you that order: http://brothersperformance.com/technotes/tuneup/firing-order.php
No you do not need to replace any plugs at all when replacing wires.
at the end of those black wires.....
yes it can
Yes, particularly if they are old and cracked. New wires will deliver a better spark to the plugs. FriPilot
Wires and plugs constitute a tune-up. DO NOT gap the plugs, it will ruin the platinum coating.
Changing spark plugs is pretty simple. Disconnect the battery, remove the wires to the spark plugs from their location, remove the old spark plugs, put in the new spark plugs, plug the cables to the right spark plug and reconnect the battery.
try changing the spark plug wires also
The main reason a car misfires is because the spark plug wires are not installed correctly. Check the car's firing order to ensure the spark plug wires running from the distributor cap to the spark plugs (in the cylinders) are in the right order. One or more spark plugs could be damaged or worn so the firing order is correct, but the spark plugs are not sparking into the spark plug wires to ignite the engine.
No. There is nothing involved in changing plugs that requires or draws electrical current.
Disconnect the battery, remove the spark plugs wires and boots and remove the spark plugs. Put in the spark plugs, replace the spark plug wires and boots, and connect the battery.
they could be bad spark plugs as in not a very good brand. or maybe you didn't put the wires back on the right spark plug.
one of your wires is most likely loose so check that and if that isn't it make sure your spark plugs are tight
