no start unless???
got a 95 bronco with 5.0, sometime when you try starting it when its cold it wont start unless you feather the gas a little and then when it does start it sounds like its loaded with fuel really bad until you get a couple of revs out of it to clear it out,, and it will be fine for awhile,,, would this be a fuel presure regulator problem??

could very well be. pull the vacum line and see if gas comes out. that would mean bad fpr , also check your fuel pressure at the rail with a gauge. also check your oil and smell it for gas. if gas is in the oil do not drive it anymore, it could cause engine failure

i have not checked the timing but i am almost positive that is not it,, it only does this once in awhile not all the time,, i checked the egr and it is clean and working,, i had another hint from a ford guy saying it may be a throttle position sensor

I have the same issue right now. all the top end sensors have been replaced and no codes come up at all. I am changing out the Distributor on it now do to the TF Ignition module on the side it. I have been told that this could be why I am experiencing some similar issue. But Mine also feels and sounds like it is missing when it is at running temp right around 1500 to 22-2500 rpm (this is when it is most apperant)
