Rough idle 200

posted by  someone claiming to be G.B on  Mon Mar 31 23:44 CST 2003 [RELATED]

My 83 wagon(EFI)is running rough when cold.Engine hunts but kicks in at 2000 rpm then runs smoothly.Performance improves a bit when it warms up but still a dead spot on acceleration.Mechanic says any number of things could be causing this so he was hesitant to try to track the problem -not knowing the history of maintenance.What checks should I be doing to try to trace the cause?Any advice appreciated.Thanks.

    Vacuum leaks, such as the intake manifold gasket or injector seals, are a common source of rough idle and poor low speed performance.

    But then, so's a varnished-up throttle body.

    And crummy ignition components don't help, either.
