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!

SOURCE: Car will not downshift upon acceleration..."kickdown"

Most affordable possible solution is to give it a transmission tune-up. Transmission number one problem is neglect. Change the oil, filter and pan gasket. You'll probably need to take the pan off, very messy job. Take the pan off, carefully scrape all old gasket material, clean the pan with dish washing soap, dry it completely, put a bottle of Lucas for transmission in the pan. Put some Indian Head Gasket Shellac Compound on the pan gasket surface. Set the gasket on the pan, keep the gasket on the pan for three minutes then install. Don't put any Shellac on the transmission gasket surface nor on the gasket. Follow recommended directions for filling the transmission with oil.

SOURCE: cadillac sts dead battery cant open car with

Don't you still have a door key?Otherwise jack up the car and remove the engine under body cover.Between the radiator support and the engine are some hard lines.Remove the two brackets holding them,this will allow you room to get to the starter.Hook the red end of a jumper cable to the red battery cable that's connected to the starter.Black to a suitable ground and charge the battery.A battery charger is easier to use,use that if you have one.If jumping off a car make sure the cables are hooked to the dead car first and grounded to the engine not the battery of the car doing the charging.Sure hope this helps!

05 cadillac sts left brakelight is dim

The globe may be in backwards. Twin filiment globes can sometimes be installed back to front. See when you have your running lights on if that one is brighter than the other, if so it is backwards, Otherwise the globe is probably getting old & blackened & need to be replaced.

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.
