How smooth is your idle?
Is your idle dead smooth or some what lumpy?
My car is doing this weird thing where it would "puff puff" every 10 seconds or so, and the idle gets rough. Then it clears up and its the same "puff puff". I hear this sound come out of the exhaust with the windows down. I dont know how to get it to be smoother.
I was thinking of tweaking the idle screw just a little bit, it seems to run a bit smoother if I keep my foot very lightly on the gas.
Your thoughts?

How do I clean EGR? IAC I have an idea.
What do you mean if closed loop fueling is incorrect? You mean fueling at idle, if I understand correctly?

If your setup is at 13.3 at idle then you should be fine. Maybe it's too rich? Are the plugs old/fouled? How old are the wires?
If my setup gets around 16.5:1 at idle it'll stumble and puffpuff a little. On a side note I can get around 16.8-17.1 on the highway before it misfires. I normally keep it around 16.1 though.

im having a problem with my idle too. but im already running HiRes. paul and i did the high hires mod today and did some tuning too, but the idling problem didnt go away. itll idle at about 15.1 afr. but it jumps/spikes to about 18.0 + afr all the time. im thinking it might be my plugs and wires? maybe a problem with my injectors? anyone have any insite to this?
