Ok guys....got a 94 SOHC that is experiencing a bit of hesitation in the first bit of throttle..but levels off...plugs, wires, dist. cap, airfilter, O2 sensor, etc. are good. I even broke the throttle body down and cleaned it good....no help. I figure it could be one of two things....catalytic converter needs replacing OR the EGR valve need replacing......if it turns out to be th EGR, how difficult is that to replace? I know I can do it, just never done it before.

thx
