  1. 1999 Mustang Cobra IAC restrictor?

    4.6L Tech
    My 1999 SVT convertible has the issue that many 4.6 cars apparently have, which is that it holds rpm's too long between shifts or in neutral. There is an easy fix where you put a drilled copper pipe cap into the IAC feed which restricts the idle flow, but I can't seem to find the feed on my...
  2. Need some piece of mind after accidental downshift

    2011 - 2014 Mustang GT Tech
    A week ago I traded in my 2011 V6 and brought home a 2013 GT with 10000 miles on it. I could't wait to get back to a manual car, having made the mistake of buying the 2011 automatic because of an incredible deal. I instantly fell in love and have been loving it more an more. My roommate has...

  4. Does skip shifting damage the synchro's

    2011-2014 Mustang Talk
    so I tried a skip shift, after reading about how the 11-12 mustangs had skip shift built in. It worked great smoothest shift I've ever had, just went a little above 4000 rpm in first and shifted to fourth with rev matching, much easier then rowing through the gears. But I've read that this...

    5.0L Tech
    I check the belt on my brother's 95 Mustang 5.0 and it was broken. I checked the belt and noticed that it was burnt on one side. What could've caused this problem? I never had any experience when it comes to fixing cars.
  7. 1968 Mustang Rev Limiter?

    Classic Tech
    So my dad just got a 1968 Mustang with a 289 V8. The guy he bought it from said it used to be a race car, but stopped racing, put a rev limiter on it, and let his daughter drive it for a few years. He didn't elaborate on the function or location of the rev limiter, so now we're wondering if...

    5.0L Tech
    Hello, My 5.0 88, Mustang dies at red lights. It will idle normal, and then it will hesitate and then roughly idle and then die. If I try cranking it, it will not restart. If I hit the Distributor, then it will restart. It might die, or keep on going, but the idle will still be rough. It...
