Engine acceleration problems

[Tom]

My 92 MX-3 V-6, 1.8 Litre has 145,000 miles on her. It seems to run great with new plugs but after about 1,000 miles or so the acceleration it starts to bog out under a load, especially in 2 gear and just barely a little pressure on gas after acceleration when I first start out. I'm stumped. Done new plugs, wires, cap and rotor, air cleaner, etc.<P>I've took it to the dealer and at 1st I was using autolite plugs. The dealer introduced me to NGK plugs and the problem dissappeared. Now after 1,000 miles the problem keeps coming back.<P>Any opinions or suggestions???
