Unknown noise
 

I'm having a loud rattle, vibration, or knocking noise at 3500 to 5500 rpm in all gears at around 75% throttle and up. I can't get noise to happen in park and it's not a constant noise. Anyone else have this symptom? Here is a short video of noise.

That's what I think every time I hear it. :-(

i get it too, its apparently from your shifter forks being worn unevenly

Warranty cover it?

Doesn't seem to be coming from shifter, sounds like it's coming from under hood.

If I'm hearing it correctly I think mine does it once in a while as well. It just kind of does it randomly but it seems to only do it when I've been running the A/C.

Going to schedule appointment at a mod friendly dealership. Have them do a shifter check.

Thanks for replies.

Do you have any aftermarket intake?

Yes, click on my signature to see my list of aftermarket parts.

Mine started making a weird noise like that too after I installed my true cold air intake..... Did it start happening after you installed the intake?

I did all mods in a short time, but it was mostly noticed after ECUtek flash. The power increase made it louder. After dyno tune for E85 it has been getting louder and louder. Got intake about 3 weeks before ECUtek, couldn't hear it much over exhaust and intake noise.

@FA20Club Toni noticed noise coming from car during dyno tuning with hood open. Just said it sounds like something is rattling.

maybe its the cam timing adjustment change during that Rev band making you worry
