Ive been around really loud cars lately and its messing me up. even at a light with only ONE of them next to me my idle is all over the place. a WOT shift isnt happening next these cars and its VERY frustrating. is there anything people are doing to stop these vibrations to the MAF(dynamat?insulfoam whatever!?) without going aftermarket ecu just yet.

 

put the stock airbox back on. It's designed to absorb most of that

At the very least, most aftermarket intakes and open filters don't anchor the MAF sensor wbich makes them way more prone to vibration

 

so support the MAF as much as possible. anyone try dynamat around it? its that supposed to dampen vibrations
