Please help -- nobody responding

I'm wondering if someone would be kind enough to help me understand the following problems...perhaps someone can find a connection between them. I'm not car saavy, so any descriptive information would be helpful.

I purchased a 1994 Bonneville SE with 116K miles on it. Seems extremely well maintained. The front ball joints/bearings? and computer was just replaced by the previous owner...here is what I'm noticing:

1. Security light always on

2. Engine seems hot under the hood (hotter than I'm used to anyway), but the temperature sensor never goes past 1/3 of the way up, so it may just be a hotter engine.

3. The car stalls occassionally while at a stop sign or while slowing down (like taking a turn into the driveway.)

4. The car seems the rev very high initially when I start it up. It calms down once I release the key, but it just starts up and revs like mad for the half second that I have the key turned.

5. When I am breaking, the breaks feel a little "lumpy", as if it wasn't perfectly round, so that I can feel the shudder in the steering. As I slow down, the interval between the 'lumps" slows down of course.

The stalling is the most fustrating of course. I am specifically wondering if the break thing could be related to the new ball joints/bearings? and if the security light or stalling could be due to the new computer. But, if you can tell me anything about these problems, that would be helpful. Thanks in advance.

Seems like it will be a great car, I just don't want to be pouring hundreds of dollars in changing crap that is fine.

Issue 1) So the security light is on solid while running, off, locked and unlocked???

Issue 3 & 4) Could be the Idle Air Controler (IAC). Clean it as well as the throttle body. Remove the TB, remove the 3 sensors and clean the TB with STP throttle body and intake cleaner and a brush. Get all of the gunk out. This is inexpensive way to eliminate the IAC as the culprit and it's good maintanance too.

Issue 5) If it feels lumpy during braking only, it's probably warped rotor(s). If it is at any time then at could be a bad tire, rim or improperly balanced wheel.

Thanks...I'll try those things
