'89 gtu - A cold misfire

Post by Fuel »

Hey all,
the car runs rough at cold
start for about five or so
minutes until closed loop op.
After that it seems to do
pretty well with an occasional
hiccup. Did the idle relearn twice.
The first time the cold miss went
away for a day or so, then it
slowly started coming back.
Unplugged TCC with no
relief.
Plugs are new. Wires are old
but intact. Just changed a coil
pack not long ago.

Bad wire to the #1 cylinder
replaced with a new set
also changed out the other
two OE coils which were
still good, just wanted
everything new. Now she
purrs.

Hope this helps
