I have little information in your story. I need MUCH more. FIRST of all.. a car doesn't miss
when you are only in low rpm. it is either missing OR it's not. based on what the story is,
you may have a dead piston. anyone can replace spark plugs, but do you have proper gap
in each plug AND the wires are on the right plug?? If you lost track of wires and which plug
it goes then yes, it will sound HORRID and sound exactly like it is missing because the
wires are in the wrong slot. I don't know the fire order for that vr6. Take your VIN to a shop
or dealer and they can tell you the F O most likely. take a pinch of masking tape and mark
your plug wires when changing them. Being confused over your wires is NOT where you
want to be. your wipers are probably on a timer and you are not sure how the timer works,
BASED on how much information you have given. Good luck
