[DML] Slightly rough hot idle

["soma576" <Soma576@xxxxxxx>]

Hey guys,

Been a long time since I had to troubleshoot an idle problem, so maybe someone can remind me where to start!

Last year, and now this year (just started it up this week after sitting all winter) I've noticed a somewhat rough hot idle.  The car starts easy, seeks for a few seconds as normal when cold, then settles down to a steady idle around 700 RPM.  However, after driving for awhile and the temp gets up, when you roll to a stop it warbles and every now and then surges slightly like it's going to seek.  Then it settles down to a slightly rough idle, sometimes surging every few seconds.

I recently changed the fuel accumulator, made sure everything was good in the gas tank, and regapped the plugs (they were all in good shape and didn't show anything bad last spring).

Any good ideas where to start?

Andy
