Car Not Warming up like it should (choke)

Discussion in 'Fox 5.0 Mustang Tech' started by Peg8687, Dec 17, 2003.

  1. The car doesn't raise its RPMs when its cold to help warm a choke on Carbs

    Also i've noticed sometimes when starting the car after youve driven starts before it acually should...Like instead of turning over 3-4 times its fires as soon as you hit it, and shutters around 300-500 RPMS then jumps to idle...

    Any idea?
  2. Well, the idle up should only be for 20 seconds or so right on startup. ALl the 5.0's i have worked on never idled more than a few seconds at a raised idle before they settled down.
  3. it doesn't idle up at all...when it starts normal it'll shoot up to about 1500 then settle....or do like i said earlier when it strarts b4 it should
