    I would suggest you take the left front tire off and go though the wheel well. Use a standard 3/8 ratchet, extension, and a swivel joint. Don't use bosch plugs on this engine as the taperred bottom tends to cause them to get overtorqued. Stick with AC Delco plugs.

    I agree, thru the wheel well is the only way to do it, it is a bitch and it will take a while to do it.

    Ok I keep hearing how hard it is to change the #3 spark plug, but I just changed mine on my 1999 s10 zr2 and I went through the wheel well using a standard 5/8 plug socket and a wobble extension and had no problems what so ever! So all you need is a floor jack, jack stand (for safety! Don't ever leave a vehicle on a jack) lug wrench (I use a 19 mm and impact) 5/8 plug socket (don't use a regular 5/8 deep well! Broken plugs suck) a 10" wobble extension and 3/8 ratchet. Took me about 45 minutes start to finish. I changed plugs wires cap and rotor and a high fire coil.
