Here are some periods, you can borrow them for your post

..........................................................................................................................................................................................................................

Have you checked the plugs/wires?
Checked compression?
Whats the fuel pressure at?
Any vacuum leaks?
Replaced the fuel filter?
Tested the TPS (Throttle positioning sensor)?

Yeah sounds like it might need a general tuneup.

Sounds like a grounding out spark plug wire, or bad coil. Maybe it jumped time.

sorry was in a hurry, plus im not great at grammar bare with me.

Plugs and wires are new.
Last time i checked it was good ill do it again.
Into sure of fuel pressure,will check
How do you check for leaks on the vacuum?
I havent replaced fuel filter yet.
How do i test the TPS

what should the timing be ill check it

Tune up

what would u consider a good tune up?

Plugs, wires, cap, rotor and coil. Check timing after.

i just put new plugs and wires not to long ago ill pick up a coil, cap and rotor, how hard is it to do the cap looks like it might be a pain since its sits under the intake

It can be a bit tricky, but can be done with basic tools.

I don't remember if I had to pull any of the wires, but I do remember setting the old cap and new cap side to side and swapping the wires one by one to make sure I got the firing order right.. But not an issue if you know where #1 is and have the firing order with numbered wires. A lot of aftermarket aren't numbered though. But possible to change with the intake still on there.

Timing should be at 10*. make sure the SPOUT connector is disconnected and the engine is warm. The spout is on the passenger side of the intake manifold kinda below the Idle Air Control Valve.

i changed everything you said here i changed one of the fuel filter but i have to change the other (i didn't see it till after i put the other one on)
its still act like it not getting spark of fuel when i give it alot of pedal

 

[getmoney06]

nothing ?

And it's not throwing any codes? Checking for vacuum leaks is easy. Spray starting fluid or equivilent around the hoses and whatnot. If the engine revs, you have a vacuum leak. Maybe check the compression. The second post is what I would do. Check that all are in working order, though i doubt the TPS is at fault.
