type44 rough start and rough idle when cold... Solved with Techron

[Dave C]

Hi Ya folks,
I was following this thread last month because I had a sort of similar
problem with my 89 100 with NF engine and 160 k miles on it.... Poor
starting when cold with increasingly longer cranking time the colder
it got.  Below about 10 deg F it might not start at all.  I had
replaced plugs, cap and rotor recently and the plug wires seemed to be
good.  Engine coolant temp sensor checked OK.  Injectors are original,
so I began to suspect they might be the problem and began pricing a
new set.  Meanwhile I put Techron injector cleaner n the gas tank and
within 100 miles the problem seems to be 100% gone.
