OK I am going to try to explain this the best I can. I am new to mustangs and V8's in general. I purchased my car with existing issues. It ran like crap and seemed to be out of time.

So I replaced the wires, cap button, plugs, pulled the dizzy and reinstalled at TDC and set the timing and adjusted the fuel pressure.. was at 50psi now 39psi at idle. Now just assume I am not a total idiot and did all that right.. :) Possible I screwed something up..

The car still runs like crap, Idles rough and I punch it it falls on its face, sputter badly. What else can cause this behavior? About 5 things come to mind but I dont want to just start throwing parts at it..

Looking for some ideas any advice would be appreciated. Bad Dizzy? Vac leak? bad ECU?
