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. :(
