Idle Jolt during warmup

Hello all,

It is winter time, and even in balmy California mornings drops to around 40F. I have noticed that during the warmup, my car will experience idle jolt (when at stop light for a while, the idle speed would drop and come right back up). The car is now 10 years old and have exhibited this annoyance for 5 years. It drives find when warm.

Any hints on what to replace or diagnose.

Ben

Is that a DIY job? Any procedures?
