It COULD BE the electronic ignition computer. On engine startup several sensors provide information which the computer uses to to reset ignition timing [slightly retarded] for a cranking speed well below idle, to set the fuel mixture temporarily to rich, and probably some other things I can't think of right now. Any time the fuel mixture is over rich, the knocking tends to increase. It seems that one or more of the start mode adjustments is just slightly out of specification. Not far enough to prevent the engine from starting, but just far enough to allow "pre-ignition," resulting in a few "knocks," until the engine RPM comes up, and the computer has more data with which to work, and the mixture is leaned out for fuel economy and polllution reduction.

If it is more of a ping than a knock then just try running some higher octane fuel in it. If is more of a knock it could be a rod or crankshaft bearing. If it is definitely a knock you should get it looked at right away.

1999 Cadillac Eldorado gas?

What does it say on the dash? If it says "Premium Gas Recommended" or "Premium Gas Required", try running a mid-grade for a while. The Northstar has a pretty sophisticated anti-knock program, so if you get no ill-effects from running 87 octane, you'll be fine. I used 87 in my 99 Deville for about 100,000 miles and had no problems whatsoever.
