Very odd noise, 4.7L - TundraTalk.net

black07sc · 06-24-2008, 12:17 PM

Recently I have noticed a very strange vibration/harmonic sound coming from the engine area at very light part throttle situations. It started a couple of weeks ago very sporadicly and now is doing it frequently. It sounds like something is vibrating very fast under the hood near the firewall and only at a very specific point where the throttle is open. This is the 4.7 V8. Was wondering if anyone else has encountered this. It is extremely annoying and I am hoping the dealer will be able to figure this one out.

The dealer has had my truck for 4 days now and can not figure out the problem, so far they have been able to rule out that it was not 5.7L envy though. They are having a Toyota rep look at it, but I doubt they are going to be able to figure it out, 3 techs have drove it and can't figure it out.
