Your car is equipped with an OBD II system and requires and OBD II scan tool to reset the check engine light. There is a port under the dash that it hooks to.

A very basic tool is available from a variety of places for about $20.(i.e ebay, Harbor Freight)

06 Cadillac STS 3.6 liter engine light flashes when I accelerate, light goes out when slow down, please help

If it is the check engine light, you would need to have the computer scanned for trouble codes.
And it should be staying on when the engine is running.

Engine light flashing cant go pass 30mph, also car shaking.. 05 sts Cadillac

It sounds to me that you have an extreme engine misfire and the engine control computer has gone into "reduced power mode" (The reason for which can only be determined by proper diagnosis).

If your check engine light is blinking, it is the automotive equivalent of posting in bold, underlined, all caps....

it is SCREAMING at you to get your engine control system checked out because you are in the process of DESTROYING SOME VERY HIGH-DOLLAR PARTS OF YOUR CAR!!! (If you have not already done that.)

Sorry I yelled, But I needed to make the point that the light has apparently been unable to make. Get it checked out and fixed ASAP!

How to reset the check engine light on a 2005 Cadillac STS V8?

If the check engine light is on, there is a problem that the computer has detected and it needs to be fixed first. Once the proper repair(s) have been made you can use a code reader that has the ability to "reset" the light. You could also just disconnect the battery for 15 minutes. If the problem hasen't been fixed the light will come back on.
