    Hi dan,
    Thank you for your help. My zip code is 60164. I dont know of any code on the engine, sorry. All I know is that it is a 3.6L/255-hp V-6 engine. They dont rebuild these and to buy one brand new is too expensive.

When i push the gas pedal on mhy 2004 cadillac cts it feels spongy and wont go

Your dts uses drive by wire. The gas pedal is actually an electrical switch connected to the engine computer which then actuate a throttle body motor which causes the car to speed up or slow down. If you mean the car won't acceleration then the throttle actuator is probably going out, this is common and you replace the throttle body assembly as the actuator is sealed onto it. Had the same problem with my 04 srx (which is mechanically the same as a cts). If you have a check engine light on (and you should) get the codes read first as there are a few other problems that can cause throttle problems, however they are less likely the cause.

I would guess that the control that changes the flow of air from one duct to the next is broken and likely have that one side in the closed position. Old systems used the slide lever to open and closed ducts, but newer stuff, especially cadillacs, use a lot of electronics so it is probably controlled by a motor. I would have some diagnostics done to see if the motor controlling your duct work has fried.

I have a Cadillac CTS 2004.. 3.6L V6 engine. I need to know if my car has a dipstick? And is it to check the level or just a hole to fill.

I too have the 2004 CTS.
Just today, my dealership checked my transmission fluid level because I have gear noise.

There is NO dipstick!

The car is put up on the hoist with motor running and transmission in neutral.
There is a fill / level check plug located on drivers side of transmission through which the level is checked.
