Default 93 lesabre

I'm looking to possibly buy a 93 lesabre limited it has 83K on it. I will be having my mechanic look at it before I decide to but it there are a couple of little things that I have noticed about it that I had questions about.

When it is cold the idle is a little rough and will jump up I noticed when I rev it by hand a little and let go it will take a sec for it to settle back to idle. I feel like this is probably just the TB needing cleaning to remove the gunk. They have replaced the spark plugs but not the wires I will be checking the service records to know when this was done.

I was told that the ABS light it on due to the Wheel Spin Sensor control module not functioning correctly and the part new is ~$800.

The car seems a bit sluggish not too responsive when given %100 throttle. I'm assuming this could partly be due to the WSS. How can I disable this to check it? Also I figure that cleaning the engine and fuel system should remedy this.

The gear ratio is 2.84 I had a 93 bonneville se what was the gear ratio in that and if it is different how would that affect the car in terms of response, pick up and MPG?

Thanks in advance.

Eh, it prolly could use a good tune up an all.
Your gear ratio on your Bonnie was/is a 3.06, which is why you get the good dyno in the butt feeling, compared to the 2.84, it gives you better fuel mileage in the long run, but shitty take offs.
I just swapped my diffs from a 3.06 to a 2.84. Thinking about going back to the 3.06. Love that take off feeling.

I will be picking this car up today after work going out to get my after market HU installed and stop at the car parts store.

I was wondering how long on average will it take to do the TB cleaning if it has never been done and this will be my first time to try doing it? Also after replacing the TB gasket should I be able to reuse it at a later date like in a few months? Almost forgot the torx bolts will the swissarmy style wrench work?

I will be driving to Louisville on friday 100mi each way so im wanting to do it tonight if possible.
