Did you scan the PCM (computer) for diagnostic codes?

OK... not much to work with here.

Describe the problem more fully. When does it sound like it's "cammed" - at idle, under heavy acceleration, normal cruising, all the time? Do you mean is has an unstable idle, misfires, etc.? Does the exhaust smell or fuel?

like when I turn it on it's sounds cammed, and the longer I leave it on it starts to idle, and wanting to turn off' I press the gas and goes quiet for a lil then accelerates.

Do you mean as the engine warms up it starts to idle more smoothly?

What EXACTLY do you mean by "sounds cammed"? Do you mean it is a very rough idle... it surges, it lopes?

You have to explain the problem clearly, or there's no way to help you.

cammed by it wants to turn off' like it idles even more roughly after it warms up

How old are the:

-spark plugs?

-spark plug wires?

-O2 sensors?

Does it ever actually stall?

Rough idle can be caused by a faulty EGR valve, failing to close fully.

Is the SES light on?

Has the engine been modified in any way? How many miles on the engine?
