It feels like the motor keeps shutting off and coming right back on. The oil pressure and tach will drop for a sec or 2 and I will give it gas and it picks back up. It's real bad on the interstate. I need help I have put new plugs in it and still does it. Going crazy please help

 

you likely have a ground problem or connection problem read up on those symptoms......somebody here will chime in with a pretty good cure.
