well, every now and then after i do a nice run boosting around 9 psi and i come to a stop light my idle will become erratic and vacuum drops from the normal 17 to about 10 or 12, but if i rev it or drive it a little more it goes back to being normal. i hate it because i can't diagnose it because it is intermittent. anyone have this problem before?
thanks

On our car, try key dance and see what it gives you. My car in NT form sometimes does that where the RPM suddenly drops and it feels like it is goign to stall out.

When i swapped out my fuel filter and change my plugs it went away.

How about your fuel pressure readings? does it look normal?

it could be that you fouled your 02sensor momentarely (sp) after boosting and hence runs a little rich, but after you start driving the sensor cleans itself out.

hope this helps out.
