Idle Problems
Guys I've been having a little idle problem. For a short second im getting a drop in rpms, then it corrects itself. I'm monitoring my air fuel ratio and during that second im getting a lean spike, which I think is normal for if your cars rpms drop for a second. Any ideas?

i have a similar problem but only when driving and in traffic. i would let go off the brake pedal and the car will then move and rpm will go up and down by itself. is this the same problem you have? if so hopefully someone has an answer to this. possibly a vaccum leak?

What else is happening during that moment? Cooling fans cutting on? A/C compressor cycling? Engine cold? Warm? Hot?
Have you scanned IAC and TPS values during the condition?
