How do you get to the spark plugs to change them in a 1999 Pontiac Firebird?

I have the v6 and it is difficult to do. You have to get 3 of the plugs from underneath the car and you will also need extensions and a swivel-joint . Good luck, it's a tough job! If I wasn't so cheap I'd send it to the shop. LOL.

You can rock the engine forward by unhooking the straps and pulling the engine forward with a rope or cable, or by putting a board on top of a floor jack and lifting the oil pan a little bit. Do either of these and Bob's your uncle!

Improving on the first answer... It's easier than it looks but like the first guy said you will NEED a swivel joint extention, also called a unviversal or U-joint as well as one or two short extentions. If you have a shortie (short handle) rachet, it comes in handy!! Plugs for cylinders 3,5 and 6 must be accessed from under the car, 1, 2 and 4 can be reached from under the hood, though it certainly helps to have someone under the car that can see the plugs and help direct you, especially on cylinder 4. Heres a diagram for those unfamiliar with cylinder numbering, hope this was helpful.
