weard stuff

may be the spark plugs fouling out. take the plugs out(one at a time so's not to confuse the wires) and check for carbon buildup or oil buildup. Use a Shop Towel(not a paper or cloth towel) to clean it and take a piece of sandpaper(I recommend 150-grit) and very lightly sand between the center electrode and the side electrode. If that ain't the problem, it may be a dirty fuel filter or dirty injectors, or carbon deposits built up on the valves. If it's a fuel problem, run some Sea Foam thru there. Pour it in the tank just before filling up.

ok thanx i got good plugs new filter and the fule is there so its not the pump im leaning on the fule pressur reg.? and i got a new computer cause it had a 94 camero comp, it still wont skan for coads on the diaog....

My '03 Ford police cruiser ran rough like that when I first got it. I ran some of that Sea Foam through it and ain't had that problem since.

any idea why it wont read a code it comes up error

the scanner says "error connecting to vehicle" or something like that?

i tried to skan it but all it ses is error so i changed the computer cause it was a junkyard comp, out of a 94 camero and still ses error on the code reader..
