When I first start the car it runs rough and will idle down and stall. Once
it smooths out it is OK in park or neutral but stalls as soon as I put it
in gear. Once warmed up, I can get it in gear and moving but it hesitates
badly and stalls frequently. If I can feather the gas enough to build up a
little speed and RPM it will suddenly take off and run fine at highway
speed. If I slow down with out keeping the RPM's up, it will start to
hesitate again and may stall. If I can ride the brake and keep gas to it
with RPM's up it will stay running and go.
When it is very hot, like say driving 50 miles on the highway and then
stopping for 5 to 10 minutes, it will turn over but not fire. It has to
sit and cool substantially before starting again. Once started I am back
to the same running problem described above. Any ideas will be appreciated
and pursued. Thanks.
