Daily driver problem

[wheels]

I no this may be the wrong area to post but some of us use newer motors. I have a 93 straight 6 with a 5 speed standard run all the time but shutters at times at any speed. I understand this is a common problem but no one seems to have pinpointed the problem. My fuel supply is good plugs fine, distributer good, wires good I am lost. Many things have been mentioned on line but not pinpointed and I can't afford to replace everything untill found. Any help would be appreciated.

Best advice I have to offer is go over to FTE and post this question in the six cylinder engine forum. Free to join and really a decent site. Not as much fun as this one but helpful none the less. IMHO!
