IAC is adjusted by the little screw on the top of the TB. 2. O/D gears break often. They are in the instrument cluster themselves. 50resto.com sells the gears that strip out.3. You need a speed cal to adjust for the different gear ratio. You can buy those from most any mustang parts dealer4. 5.0s are well known for not starting up or dying the first time you start them up. I usually pedal it for a second and let it get going then it will run just fine. You may very well have a bad IAC though. 5. Check your PCV system, as a clogged PCV filter will stop any amount of crankcase ventilation. Your motor may also have blow by and be causing the oil to come out by force. However leaky rear mains are a well known common thing on 5.0s.</blockquote>
