hey all,
i know i should not have done it but i did.  i did not let my van warm up
late last night to get home.  it was very cold and when i pulled out on to
the road and accelerated the van wanted to almost stall out completely for
about a mile.  then i guess it warmed up and ran fine.  what causes this
sort of thing?  i also experience an erratic idle.  the idle is perceivably
set at 1000 rpm.  however, occasionally it will idle at 1300 and up to 1500
rpms. then it will fall back down to 1000 rpm after driving awhile.  sound
familiar to anyone?  i changed the fuel pressure reg and no help.  i have
cleaned my injectors with slick 50 fi cleaner for the last few gas tanks.
no help there.  the van still sorta hesitates in third gear at high rpm like
4000 rpm.  could it be idle stabilizer? running too lean? too rich? o2
sensor? temp 2 sensor? fi injectors?  i am going crazy here.  i imagine that
these symptoms are common to any failure in the fi system, correct?  ugh...
thanks
