1. Dies out -- fuel or compression issue.
3. engine codes, yes, there is a way to hook up a light or test meter and count the flashes or swings of the needle. Too cumbersome
4. K member is bolted on
5. Polished intake... talk to Vinnietbird on this net. I've seen pics of his work and its great!!
6. Quadrant is above your right foot. If the radio is out, you can see it easily or if you can take the seat out and lie on you back, you can see it. You can also see it with the door open if you get down low outside the car (just barely). Its easier to put your hand up there and feel it... stock is plastic.
