Sometimes if you wait a few hours go back and it will start it is the fuel filter. Can you hear your fuel pump make a humming noise when you turn over your key if you can't open your gas lid stick a screw driver down the hole to open the flap and put your ear near to listen for the fuel pump coming on

Can spark plugs cuase this problem if 4of them is bad

Usually it will run but just really rough you can't take one out and it will still run it will have a really bad miss

How did this start anyway? When was the last time you drove it? You have to narrow down the problems to find a solution as much info as you know of before the situation happened the better it will be of finding out why

I drive it just fine everyday I clean then change the throttle body put 2 spark plugs in it then it was fine tha old throttle body was making a noise and would not stop,at first that sound was only when I start the engine.
