It could possibly be your mass air flow sensor is dirty. Go to autozone and buy mass airflow sensor cleaner, take the sensor off the car right next to the air filter on the passenger side under the hood on the intake with a screw driver. Read the directions on the cleaner carefully, apply the cleaner to the sensor. The car may run rough for a few days then clear up and the restricted performance light should go off. If the restricted performance light doesn't go off and the car still runs rough take it to auto zone and have them put it on their computer free of charge and it will more than likely still say it is the mass air flow sensor, which means the sensor is bad and needs to be replaced. The cleaner is around ten dollars and the new sensor is about $160.00, but let the cleaner work it may feel like the car is falling apart after the sensor is cleaned but dont take any action unless the car still runs rough after a week to a week and a half.
It can be that the brake sensor is sticky/faulty and it is conflicting with the cruise control. (CC says go, brake says no). When these conditions occur, the car goes into safe mode and disables the cc.
What is a thermostat light?

There are a number of things that would make a volt indicator light to come on in a 1998 Buick la Sabre. The main reason is voltage feedback or a problem with the alternator.?æ
Do you mean the check engine light does not come on when you turn the ignition on? Possibly the bulb is burnt out.
Loose connections from the body electrical strap to the engine. You said battery but do you mean the charge light?
Easy, fix the problem that caused the light to come on in the first place.
Yes, illegal, will not help performance, will cause check engine light to come on, ................
Not necessarily.
