I have a 1992 Mitsubishi 3000gt VR-4 (Twin turbo)
Last night I was driving… not even pushing my car or anything. I go through 1st gear fine, then when I hit second, out of nowhere I hear this loud air escaping sound come from under the hood around 3000rpms. As I went up in rpms, the sound just got louder, so I shifted quick.
It sounded like if I just tried to go through it, it would explode or something. I looked this up and found somewhere it said to try tightening the clamps on everything under the hood, so I did that. None of them were loose but I did tighten them a lot.
I also looked at my (boost?) gauge (gauge on the far right in the car) and it seemed like it was stuck at halfway and moved very little when I was driving. I was going to have a person try to feel where the air was coming from when I revved it in neutral but it doesn’t seem to do it in neutral…
Never heard it before and I need to figure this out as soon as possible. Trying to sell my car and this happens… Any help is appreciated. Thanks.
