shudder

  1. shudder when idling

    Engine Topics
    I have an 86 that shudders when i go into reverse, but mainly when idling. Also when idling in drive I get quite a vibration...which goes away when I step on the gas. When I bought it (which was recently) , it had sat for a year beforehand. I've changed the oil, ran some fuel system cleaner...
