2002 Ford Explorer Sport Trac 4.0 SOHC 185k Problem: doesn't want to start cold unless I turn key to run a few times beforehand. once it kicks-over, it wants to die, rpm's up and down, until finally smoothing out. poor idle. everything else works great. I've already tried and replaced: alternator battery air filter Fuel pump and filter MAF sensor IAF sensor EGR valve and vacuum solenoid valve PCV valve vapor can vent valve spark plugs and wires ran compression test: 200, 180, 180, 180, 180, 180 conducted smoke tests, propane test, starter fluid tests for vacuum leaks tested fuel pressure: at 65 or above took to dealer for diagnostic: they said retrieved CTC P01125 TP sensor intermittent circuit fault and said it had vacuum leak at the upper intake manifold and gasket area and needed new throttle body. I replaced intake manifold gaskets and new throttle body. NOTHING FIXES IT!!! any ideas, suggestions, or solutions would be greatly appreciated. I'm at a loss.
