1994 celica st bucking

[bcman14]

I have a 1994 celica st 5-speed. It started bucking in late november, maybe due to the cold weather. I also had a custom Specter air filter on it so i put the stock filter back on thinking this may have been the problem. Turns out it solved nothing. It seems the car bucks while at the low end of the gear(lower rpm's). But if i run through the gears with my foot in it there is no bucking. I have checked the air hoses for cracks and there are none i also have cleaned the throttle body which did not improve anything either. Almost seems as though there is a miss fire? Suggestions would be greatly appreciated. Thanks, Steve

sounds like your fuel filter.
