i did the air/smog pump delete, and since then if i drive with ac on every time the ac clutch kicks, the pedals/steering wheel vibrate and make a harsh noise. Except when it is in park, everything is normal. But it seems to intensify everytime i turn or hit the gas a little bit. notice in mainly at slow speeds. Belt tension seems fine, i used a 96.8" 6 rib belt just like the tech article says. so, im a little confused. Ideas?
