If you mean rpm going up and down no there is none of that when the AFM is disconnected.. btw by rough u mean if I hit the gas and does it make a rough sound then yes there is a little roughness/sputtering/small pop sound. It happens even with the AFM connected. The car wants to stall out it barely reaches the point when it hits 500 rpm, but sometimes it does stall out. The last thing I changed were fpr and took out AFM (I think I dropped it) and the icv air hose got disconnected, but I changed the air hose with new one and sealed the crack hose at the intake L-shaped one.
