The beep normally means the engine control computer has seen a fault and may or may not have set a code. Sometimes it can be quite a bit between the failures so the beeps can be sporadic. Ideally you should have the engines scanned and there should be a code stored that will indicate the failure. In some cases you will not find any codes stored even though the beeps occur. In my experience this is often caused by a failing idle air control so pay close attention to your idle quality as that can be a dead giveaway even without setting a code.
