Just a little word to you about what your are gonna change. If you are gonna change the plugs make sure you change the wires as well.
I am going through something similar with a car of mine...which shall remain nameless. I have a Chuggle, surge issue at or about 1900 - 2400. I have changed the plugs, wires, EGR valve, EGR Solinoid, MAF, injectors, 4-O2 sensors, cats, T-Stat, TB and Fuel runners. The last thing I can do is replace the opticrap system that it uses.
After this the only other thing it could be is valve float, but I would notice it more through out the rpm range.
Gremlins are a biatch to chase down and when you are doing it try to do as much of the chasing at one time. There is no sense on replacing the plugs and not the wires along with them.
Just my $1.98 worth of input
