Son's 98 30V has what seems to be a miss or tranny judder at low rpms climbing a hill. Noticed that tach drops each time miss occurs. No OBDII lights on. Misted some water on the wires and coil packs after dark and no light show, of course the wires are covered with a plastic wire loom material. A while back it lit up the shifter display but a reseat of the trans ECM fixed the display, though maybe not the problem.
Any thoughts on course of action or should I just take it to the shop? I'm very familiar with a wrench. Been keeping some old Italian iron on the road for years now
