I've been having some vacuum leak problems with the Edelbrock I installed. IT was having a hard time staying running while in gear so I assumed I was getting a vacuum leak. I got a new gasket took it out and replaced it. I used a Mr.Gasket brand and it is quite thick, unlike the paper thin one I had on before. I installed it and the car sounded SICK. I shut her off and found one of the studs had cracked in half. After an hour or so I dug it out, put a replacement in and tightened everything down. Shound better at idol but when I put her in gear she makes the sick sound and dies. I turned up the idol very high and she barely stays running while in gear. SO basically I took all day, two trips to the parts store and about 10 bucks just to make the problem worse. :: I don't know what else to do. Any suggestions?
