like the title says, i've got a 92 lx 5.0 5 speed. it wants to die out when i first start it cold. and the idle jumps around from about 500 to 1500 till its warm. then it idles very rought like it's got a cam. but its bone stock with just basic bolt on's. and when im cruising below say 2500 rpm in any gear it bucks and when i let off the gas still in gear it gets even worse. any idea what it could be?
