Did some odds & ends to it last night. Decided to go with TR55 NGK V-power plugs and changed the oil over to Mobil 1 with a Mobil 1 filter. It seems like it snapped it back to life.
I've got a meeting this morning about 100 miles away, so I can't wait to get it out on the road to see how much difference it made.
I've got to do the trans service. Trying to decide whether to go with ZZP Dex6 and their filter. Waiting for them to answer some questions.
