Use the correct size spark plug socket, ratchet wrench, extensions and possible a universal or swivel adapter. Remove the plug wire, remove plug with socket/wrench, insert and snug down new socket and firmly seat plug wire. Do one at a time so as not to cross wires uo. Be careful inserting new plug so as not to cross the threads uo and make sure the gap of the plug is correct for you engine.
They usually aren't attached per se, they fit in a socket that is snug enough to hold them. But the spark plug wires trap them into position. So you can go ahead and pull the spark plug wire off.
One thing to remember, when you go to replace the spark plugs you won't be able to see if they are cross thread in their hole, so DO NOT use a socket until you are sure the are properly seated and not cross threaded.
This sounds like a crossed sparkplug wire, start by making sure the firing order is correct, if theres a sparkplug wire in the wrong spot this would cause hard starting and the backfiring, so check the firing order first, i would of given you a firing order diagram but you forgot to list the year, make , model and the engine size. good luck and have a good day.
Those are as easy as they come these days.
Mark each spark plug wire with a piece of tape with the cylinder # written on it, so as not to mix up the wires.
Remove each spark plug wire by firmly grasping the wire by the boot (do not pull on the wire) and twist it back and forth a few times while pulling slowly. It should pop off without a great deal of effort. If it is seized and it breaks, you will have to replace the wire, or at the very least replace the terminals (if you can get some).
Use an air hose and blow around the base of each spark plug to dislodge any loose dirt that could fall into the cylinders (not absolutely necessary, but a good idea).
Remove each spark plug with a spark plug socket and extension and ratchet (I forget which size socket, it's either 5/8 or 13/16).
Check the gaps of each new spark plug (typically around 0.035 in).
re-install each new spark plug by hand (do not cross-thread them) and once you have ensured that the plug is threaded in properly, tighten the plug until it seats, and then tighten an additional 1/16 of a turn. Repeat this for the remaining plugs.
Re-install wires to the corresponding spark plugs.
Check your sparkplug and wires, make sure that there are no cuts or kinks in the wires, also be sure the plug wires dont cross over eachother. Check the sparkplugs for any builed up of composits or damage.
