Check engine light is it On?

When was the last tune-up? Charging system is it okay-if there's a problem with system voltage the parameters and actuators will no function correctly to include the computer.

Try the idle air control valve open it up and clean it, brake booster could be leaking or vacuum hose. MAF/ IAT/TPS sensors
