When reving or driving, at around 2k to 3k rpm tach needle jumps and car hesitates. at about 4k rpm its smooth. i have not checked anything yet besides spark plugs and they look OK. i will change them and see if it helps.

Usually a jumpy tachometer is associated with the ignition coil. Have that tested.
