From a quick web search, code P0014 supposedly indicates a problem with the timing advance. I would check that the you have the base timing set correctly. The computer has to be in diagnostic mode when you check it, which requires putting a jumper across two wires at the diagnostic plug. Refer to a repair manual for directions on how to do this for your vehicle. The base timing should be 5 degrees before top dead center (BTDC) for cylinder 1 at sea level. Add 1 degree BTDC for each 1000 feet above sea level (if you're 3000 feet above sea level, base timing setting should be 8 degrees BTDC).

for that cost you could have taken it to a mechanic and had the compretion tested, that is what needs to be done. at least 90psi and all cyliders sould be within 15% to that.

trade spark plug wire with another see if u get spark then

Since you have checked the above, I would start looking at the cam sensor and crank sensor perhaps. Did you try to get any codes? You need to check if your getting fuel to the engine as well. You should check the fuel filter and the fuel pump. Also, the fuel pump relay or fuse. Listen for the fuel pump to kick on when you turn your key on. You should hear a buxxing sound for a second or two. As far as the jerking, it sounds like you have low compression in your engine. You need to check your fuel pressure. You may have faulty fuel injectors. Check for vaccum leaks as well. The best thing to do is try to get a code. There is just to many possibilities it could be to start waisting money and your time. The code will give you an idea of where to check. If you can't get a code, you will have to start the elimination process. The good thing is you already changed the dist,wires,and plugs. I would start with the cam sensor and crank sensor. You could check the voltage going to the sensors and leaving the sensors. You need a voltage meter though. They might not be working. If you have another question, write me back. If you can get a code, we can figure this out. Without it, were going in the dark. I am here to help in anyway I can Arizana. Feel free to contact me.

Top Dead Center is when the #1 cylinder piston at the top of its stroke
just after the compression stroke. This is when the #1 spark plug will
fire. This location is used for setting the timing gears or chain and
for locating (clocking) the distributor. Be careful, you can be off by
one full rev of the crankshaft because top dead center occurs every
other revolution. The #1 piston is also at the top of its stroke just
after expelling the exhaust gas and just before air/gas intake for the
next spark plug firing. So, if the #1 piston is at the top of its stroke
and the exhaust valve just closed and the intake valve is just opening,
you are 180 degrees out of phase. Rotate the crankshaft 1 full
revolution. If the #1 piston is at the top of its stroke and the exhaust
and intake valves have not closed/opened, you are at top dead center
(TDC) and the distributor will/should be pointing at the #1 spark plug
wire.
To bring the motor to top dead center, disconnect the spark plug wire
from the ignition coil, remove all the spark plugs and remove the valve
cover from the #1 cylinder valves. Jog the starter (or rotate the
crankshaft by hand) until the #1 exhaust valve is almost closed and the
#1 intake valve just starts to open. Then rotate the crankshaft 1 full
revolution. When you are close, you can measure the height of the #1
piston with a screw driver in the #1 spark plug hole. Be careful not to
let the screw driver bind against the piston or the head. Rotate the
crankshaft back an forth slightly until you have located the highest
point for the #1 piston. This is top dead center.
Ensure that the crankshaft key is aligned with the timing mark on the engine block...
...then slide the sprocket on the end of the crankshaft, as shown
Install the inner timing chain so that the dark blue chain link is aligned with the matchmark on the idler sprocket...
...and the yellow link is aligned with the matchmark on the crankshaft sprocket.
Also, keep in mind your correct firing order...
Hope helps.
