01 escort stalling after its warmed up

[listentodave]

my friend drives her car down long highway trips a lot and when she its the end of the highway and pays the toll her car stalls while waiting in line at the toll booth. she said it also has a very low and unstable idle while sitting in normal traffic

any ideas what this might be?

you probably just need to adjust the tickover to give it more of an idle rev.the idle rev on tickover should be about 1100 rpm which then it shouldnt cut out when you pull up.or your choke could be sticking on abit which can cause the revs to drop and the engine will cut out or even choke/foul the plugs hope this helps cure the problem. wayne
