A quick look at the shop manual (not a "Haynes") does not indicate the need to re-set the computer. However, in previous research I came across information that suggested a scan tool would be needed to do that. I don't know.

I am planning to install Gabriel shocks for load sensing applications, rather than GM, since the Gabriel shocks have as good or better warranty and are about half the price (plus, either the right-hand or left-hand shocks may no longer be available from GM).

I want the scan tool handy in case it is needed.

I also plan to buy a new sensor and a salvage yard compressor in good condition. I may need to run new line in various places.

As far as an OBD tool is concerned, shop at several auto supply stores and gather as much info as you can. A lot will depend on how much you want to spend, just how involved you want to get, and what makes of vehicle you will/plan to use it on. Code readers are cheap, on the other hand scan tools are not !

I have the 1995 Buick LeSabre, a 1992 Sable 3.8 LS Wagon (with pre-OBD II electronics), a 1987 Jaguar XJ6 (with a primitive but functioning computer) and a 1987 AMC Eagle DL Wagon (same situation as the Jaguar). So I need something with a lot of versatility. In addition I have a 1997 LeSabre and my wife's 1996 Corsica (with the little 4).

Code readers do only that, read and display codes.
Scan tools can do quite a lot of things. They can read the codes, some even explain the code problem. They can test, activate different parts, provide what we call Data Stream info, displays of different sensor readings and much more. That is why they cost more. Keep us informed as you gather this info and maybe we can offer some suggestions to help make a wise decision.
