sup guys...i have a 2000 mustang gt, auto i just recently purchased...when its warmed up, it seems to start hard..(long crank time, then stumbles to idle and sometimes stalls) after the rough starts it runs great! no MIL (just the ones for rear o2 sensors because of the OR-H)...when its cold it still cranks forever but fires-up smooth. so far i have replaced the alternator because someone told me it was a common problem in these stangs causing a AC spike? anyway, it did not help. It feels like it needs a fuel pressure regulator but i understand these cars do not have them. I inspected the plug of my fuel rail pressure sensor and saw some corrosion on the plug though i figured it would throw a MIL if it was not connected....and inspected the ground in the trunk near the two fuel related modules. what should i do next?
