So I relearned my ecu, and that solved my idle issues.

I was getting p0505. With CEL on i had 2 p0505 and with the CEL off I only had one p0505. But I solved this.

Now I got this whistle to get rid of.

NO IDEA what this is, except, its not belts, and its not brakes.

It sounds like this


I did that test where you put your finger over the iacv hole in the TB, and my idle goes down, and as far as i know, it means no vac leak. Also burped my coolant. Sprayed the heck out of my vac hoses and found nothing. So what could this whistle be??

 

Any idea where the sound is originating from? Have you isolated the location?

Does it increase with engine speed? When the engine is warm/cold?

 

Intake? Does it do it while revving?

 

only in motion, and under normal and hard accel

 

capped off a hose... took that black "vacuum tank" out... smashed it, car runs great. my emission light on my 0bd2 scanner is now green, not yellow, and no p0505 came up!

I'm wondering... do the vac tanks for Cruise Control break often?
