460 ignition problems please help!!
My 94 f350 is acting weird at idle it will want to start coughing and sputtering and the idle will drop to almost 200rpms and almost die but then it will throttle its self back up to idle then start dropping again, and If I rev it up it will go away for a few minutes. Could this be my IAC Its my suspicion but it also will do this when I am driving it the engine will start coughing and bucking and If I push the clutch in and rev it a few times it will clear up for a few minutes so could This be My, Iac, my ignition control module or my PCM? Please help because I cannot afford to just start replacing things like my IAC Or my PCM
Thanks

First thing I would do is take it to Autozone or another parts place and have them pull the codes for you. This will put you on the right circuit hopefully. Another thought-fuel filter and hows your battery. Some of these systems wont work right without a full charge on a battery.
