Hi all,
I've been chasing this sound for months and it has been driving me crazy.
Here is a clip of the sound, I removed the center console/dash to get a clear sound for the video. At the end of the video you can hear me take my foot off the throttle and the sound completely stops.
- YouTube
I've searched nearly every forum/ YouTube video relating to this sound I and I can't seem to find anyone with the same sound/ issue. My issue I have is a raspy/rough sound upon accelerating only. No check engine light and no noticeable issues while driving, only the sound. The noise is not there when I am in park/neutral and rev the engine. My first thought was exhaust leak, I took it to my local shop, had 2 leaks fixed and the sound is the same. Since then I have replaced the following. Fuel Filter, OEM MAF, O2 sensor, oil and filter and air filter (OEM spark plugs have less than 10k mi with OEM coil packs replaces at the same time). I have also ran a few tanks of gas with fuel injector cleaner and sea foam in the gas tank as well as seafoam in crank case and the upper engine spray. I have also ran a few tanks of 91 Octane so I know its not pinging or detonation. So far nothing I have done has affected the sound, however the truck does feel smoother and more responsive since I began this process.
Could this possibly be sounds from one of the belts (AC, power steering or Alternator)or belt pulleys? Or possibly exhaust leak in the crossover pipe that the muffler shop missed? (I doubt this is the case as the muffler shop is reputable)
Any help would be greatly appreciated
