99 Solara Brake Booster Hissing
Think I posted this topic in the wrong forum, so re-posting it here - Thanks in advance for the help.
1999 Solara with approx 130K miles. Brakes feel fine, but had a check engine light and the brake booster area under the hood is hissing. Check engine said a misfire in cylinder 1?, having taken the brake booster vacuum line off, the hissing gets worse all the air going though the line, put my finger over it, gets sucked in pretty good and the hissing goes away, put it back onto the brake booster and the hissing goes away slightly but you can still hear it. When you press the brakes the hissing goes away. Also blew into both ends of the vacuum hose, check valve seems to be working good as you cant blow past the check valve. Have not put a gage onto the end of the vacuum hose as I dont have a gage, but would a low vacuum pressure make a hissing? Guessing the diaphragm/seal in the booster went bad?
That being said, I'm not a car expert so please help. If it needs a new booster, does anyone have good institutions for replacing it at home? Thanks!!!
