When I first start the car, if I put it on.

When I first start the car, if I put it on reverse, I cant let go of the breaks right away, I wait until it kind of jumps as if though it was changing on its own and then I drive it. If I release the break to right away it jumps harder. Its the same for putting it in drive sometimes.

Also it takes a minute to accelerate ( I was told it was the spark plugs)

Last thing. If I am at a stop sign or a red light holding on to the breaks, the RPM runs to the 2 instead of idling low. It sounds like im reeving the engine a little bit.

Help Please. :(
