Similar recent problem on my '96 was fixed by replacing the temp sensor (the
one that feeds the engine computer, not the one that feeds the dash gauge).
I figure it was telling the engine computer it wasn't warmed up enough,
which would affect torque converter lockup, engine idle, etc. Not sure if
the '94 have a similar setup or not, ymmv.
