It sounds like I have a blow off valve.

With acceleration it sounds like the car is sucking in air and then releasing it when i take my foot off the gas.

It runs pretty good. Pulls pretty hard. No major idle issues. It does start up and idle poor for about a second then it picks back up.

Intake has a new gasket. Exhaust gaskets are all new. Intake pipes are all all clamped down.

Any ideas?

 

Without hearing it myself, I'd say either aliens live under the hood, or the car is fine...

 

Ill check tomorrow. I hope so.

There is a slight hesitation under 2500-3000 rpm.

But its a jdm motor from a 90-92, and it feels like a bad injector.

 

Try and catch it on video? Can't say no to a Z video =)

 

^I can show you many Z videos that'd make you say "no"...

 

I took a video, but you cant really hear the sound im hearing unless youre inside the car so the video is pointless.

There is this weird sound though. Kind of like if you were to flick a piece of plastic.
