Question about 1997 Ford Falcon
Put them in but car wouldn't start. Changed leads at the top so the order was 1-5-3-6-2-4, now car starts but engine shakes etc...would love a mechanics advice
The leads are still mixed up so you need to ascertain which is number one, two three cylinder and make sure the correct lead goed to the correct spark plug and distributor contact. If the engine runs but runs rough you likely only have two wires mixed up. Pull on wire at a time off. If the engine stalls or runs worse put it back on. Do this until you find two wires that do not affect the engine running when you pull them off and it will be these two that are interchanged. It will likely be easiest to do this at the distributor end. If you do not wan to get a shock do it with good rubber gloves on or pull a wire off with the engine off and see if it starts and if it does you likley have pulled of a wire that should be connected somewhere else. GOOD LUCK.

make sure that it's firing on all cylinders....Has any one played around with the firing order of the spark plugs?....I'm not sure what vehicle it is that you have.....If the engine check light comes on, the onboard management computer has picked up a fault....take the vehicle for a diagnostic scan and that will tell you very quickly what the problem really is.

EF & EL are 1,5,3,6,2,4
EF has a coil pack under the inlet manifold the EL has a distributor
EF uses a waste spark system so 2 plugs are fired at the same time eg 1 & 6 - 2 & 5 - 3 & 4

Sounds to me like a very common problem has occured to your neighbor. If this is a SOHC engine, one of the valve seats in the number 4 cylinder has fallen out. I'm sure it has damaged the head and the piston. Stop trying to run it or you might blow a hole in the cylinder wall or break a rod or both.

SOURCE: Firing order diagram
Here is the firing order diagram for that vehicle, and if the ignition wires are not crossed then one of the spark plugs might have been damaged while installing it and the spark plug gap closed on one of the spark plugs, or one of the ignition wires (spark plug wires) has been damaged, and if those wires are over 5 years old then you should replace them. I hope that this helps you to solve your problem.
