Here’s a little challenge for ya…
Context: I bought a new to me 2019 1500 5.7 v8 94k mi. Had the pass. Side air temp. Actuator replaced, new tires, air filters. The truck has some tasteful mods including gorhino running boards, tonneau cover, bed mat, and after market air intake and filter.
The problem:
For the first 5-7% when accelerating I get this high pitched frequency noise. If I stay within that 5-7% range on the gas pedal the frequency can/will change whether I release the pedal or press it more. After that 5% it goes away completely, so when I start to take off you hear it especially if I’m being consistent on the pedal and once I start to really get on it it goes away. Only happens if I’m moving it won’t happen if I park and just push the acceleration. Due to this I can be under the hood to figure out where it’s coming from. But this isn’t a squealing belt, this is an electrical frequency noise, doesn’t sound mechanical at all.
To preface, I am a service advisor at a ford Commercail center so I have my fair share of experience in the automotive industry. I’ve never came across something like this before and thought maybe someone here might have some insight.
