ok to start off
1. when i turn car off i hear a hissing somewhere near/in the break booster area; is this normal, but if not i'm thinking I got a vacuum leak.
2.when the car is running and i touch the top of the spark plug wire i can feel a thumping. the first plug closer to the distrbuter is a slight thumping and the thrid 1 over has a slightly harder thumping than the first. my uncle recommened me to change the brand of oil, and weed out the problem from there.
3.how do i remove my exhaust. . .the bolts have 2 springs on each one. ..do i need a special tool or something.
