Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 7 days ago.

This sounds like either an ignition or fuel breakdown under colder conditions. You should check the coils/plug wires and plugs first.

Check fuel pressure under that same condition too, when it's cold.

Thanks, Ron
