Hissing noise after plenum pull - ZR-1 Net Registry Forums

1991KOTH · 05-12-2017

The car makes an odd noise when its cranking, then when it finally starts it idles up to 3000 then comes down. Hissing appears to be coming from front drivers side near the throttle body.

Also: The car is not taking anymore coolant after draining it. Ive tried jacking the car up on its side to burp the system, but only a few bubbles come out. Any help?
