Someone diagnose my cars symptoms

[EdfromSF]

Hey everyone i am taking my SVX in for a tune-up, 120,000 miles service on monday would love some advise. Here are the the symptoms:

Sometimes when i driving along it just dies on me.

Sometimes i have my foot on the throttle and it feels like the car is Hiccupping.

Sometimes when i have the cruise control on it is is driving along fine then all of a sudden acts like it can not find the right gear to stay in.

When my car is idling it is around 1500-2000rpm in Park or Neutrul but goes down to under 1000rpm when it is stoped in any of the driving gears.

But all the time despite all these issues i LOVE this car. It is smooth, comfortable, powerful and just feels a hella of a lot more solid then my 94 Legacy.

Thxs alot everyone.
