When you turn over the car it starts to shake the Motor just was requiring is this is a comment problem I am thinking of changing my coil packs but wondering if that's going to work and this is my first time owning a skyline so I need some help thanks people for your time in reading this

One of your cylinders isn't firing. Start the car up and begin removing coilpack loom plugs, one at a time, to see if it makes a difference to the sound of the engine (i.e. running on 4 cylinders instead of 5). When you pull one off and it doesn't make a difference (i.e. still running on 5), that is the problem cylinder. Once you've sussed it out...just remove that coilpack and spark plug...then re-install...should fix whatever issue you have. Sounds like something wasn't connected back properly because it was working prior to the spark plug change.

What engine do you have and what spark plugs did you put in it?

[emts]

would guess either plug not screwed in proper or coil pack not properly plugged in/on.

I'll pull all the coil packs and plugs and start again, making sure everything seated correctly.

Yeah I'm thinking coil pack plug...

It's pretty obvious if the coilpacks aren't seated properly since the bolts on the backet don't go all the way down...

check the coil 3 plugs, tape or spark not plugged correctly

Sounds similar to the issue I had last week and it turned out to be a dead Coil Pack.

Let the car idle and unplug one injector at a time. When you find an injector that you can unplug without changing the car's idle then you have found the cylinder with the issue. If for example, cylinder 3 isn't firing - swap coil pack 2 and 3 around. Run the same test as above. If the issue is now occurring with cylinder 2, you know it's the coil pack. If not, could be the injector.

as much as I'd love to see someone remove an injector from the fuel rail while the car is running

I know I just had an awesome image in my head of 42psi pulp spraying near a running engine

What plugs did you get could be the gap?

As the other has said makes sure everything is plugged in and also the ground for the plugs has been screwed back in properly
