I checked all spark plugs i did smell gas but i replaced i injector o rings about a weeks ago. And when i had it running i pulled spark plug wire on spark plug wire 1 there was no change on 2 3 and 4 when i unpluged the wires the car was wanting to die. And The motor still shakes at low idle.

I want to help, but it's really hard to figure out what you are saying. At least put some periods in there every once in a while. Just saying.
Sounds like your car might be running on 3 cylinders. You should make sure there is no flooding of the cylinder.

That's very low. To be clear, you should check compression as follows:

Make sure your battery is charged, and use any other starting assist device you can.
Remove all plugs (unplug coil, if you love it)
Install tester firmly/tightly onto cylinder to be tested
Crank and count ten compression strokes
make sure gage isn't dropping pressure (loose valve core in compression tester check valve), and record reading, repeat on remaining 3 cylinders.

If that looks like what you did, try it again, with a cap full of motor oil down each cylinder. If it jumps up dramatically, it's probably rings/rebuild time. But either way, it's probably that time.

That said, this is what these motors do. If you want to drive it, it's probably not about to disintegrate by any degree, you could drive it plenty while getting together another motor or overhaul plans/research for this one. Your rings are burnt up and will let lots of blowby, you'll have a smoky pos and will have to add lots of oil, but if you want to drive it go put a full change of 20w-50 with a quart of lucas, check it often, and keep pourin' it in... thickest cheapest stuff you can find, 20w-50 is in spec for a new KA (over like 55f or something), so considerably thickened from that won't do much harm in your motor, with it's excessive clearances. Obviously you will have to further isolate the miss to spark or fuel on cyl 1, and fix that.

Also, it'll leak really badly, because the blowby will overpower your old clogged pcv and push oil past all the seals when the crankcase pressurizes.

When you injector 0-rings went bad my 240 shook like crazy. I replaced the injectors and a few days later is started again. The o-ring got ripped some how. So this time I only replaced just the O-rings. I took the fuel rail off but installed everything else and primed the system to see if any injector was leaking. Its nice to see the bottom of the rail to see if they are leaking

I replaced fuel injectors with new ones and fuel filter it fixed the problem but now when the engine gets to running temp so much white smoke comes from the exhaust and engine where the headers are at. Any idea what this could be?

You probably have a header leak and leaky o rings. Did you lubricate the seals when you put the injectors in?

They probably still broke somehow. I would check them to be sure. The smoke from the engine bay is just an exhaust leak that you need to fix.

Would the piston rings make it smoke like it does? Somone told me to take out the plugs and pour marvel mistery oil into each cylinder and let it sit for a couple days

What does the smoke smell like? "smells like a burning" is not exactly a good description.. Your compression numbers were super low, so it could be bad rings. I would do what mechanicalmoron said and report back.
