Weird rattle
Weird noise
Hi! So my 4.2 engine has this weird noise whenever the car in D or R and i press the accelerator there is a noise like ‘ Trrr trtrtrrrtrrrrtrr 😂’ only on 1100/1300/400 rpm goes away if its more than that. This noise doesnt come when you accelerate on neutral or park it’s completely silent. There’s no noise from the engine on cold starts as well.
I was told its coming from the intake manifold hence need to replace it there’s a butterfly in it but need more opinions
