I reset my ECU and drove the hell out of right after and now I'm facing this problem:

At first I could hear this humming and it sounded like it was coming from my intake. I checked that and it was fine.

Now that the humming is gone, something is rattling...

The rattling hits it's loudest at 2KRPM, and when you start it you can kinda hear it.

I have no clue wtf is going on and I don't know if my car's driving quality is deteriorating from it. My best guess is that it's the headers, or the exhaust.

Btw I have stock headers.

My car rattles because of the air intake, make sure that it is really firm inside the engine bay.

The ECU reset has nothing to do with your rattling.

Is the rattling coming from a certain area (under the car, engine bay, etc.)?

I know resetting the ECU didn't directly effect the noise but it must have been something I did while driving the hell out of it.

I'll try to find out where the noise is coming from...

Thanks guys

Your title "Rattling as result of resetting ECU... " breeds confusion.

its because your intake piping or filter is hitting the inside of ur car

happenz to me all the time, just make sure it is securely placed or put a little cloth where the pipe/filter touches the car...fixes it ez

Hmmmm...I'm not sure if the intake is it but I will check tomorrow.

Reason being, I had my friend rev it steadily at 2KRPM and checked all around. It sounds like it's from my exhaust, or the pipes connected to my headers.

I'll be sure to check the intake again, but it definitely sounds like it's coming from beneath.

The heat sheild on the catalytic converter has done this on many cars here.
