you need a 6 inch extension, short 3/8 ratchet, 5/8 plug socket, 3/8 swivel "u" joint, (sold at sears) 8mm 1/4 drive socket deep well and 1/4 inch ratchet.
find the coil packs (6 total, three in each head.)
remove the two retaining nuts holding each coil pack using 1/4 8mm socket and ratchet.
twist the pack to break the sticking boot below.
pull up (be careful to not rip the boots however it may still happen but rare.)
remove coil packs, the rear is a little more difficult with the intake.
use 6" extension and u joint and ratchet to remove plugs and replace.
reverse order to assemble. Good luck, and hoped this helped.

SOURCE: cd error
I hate to be the bearer of bad news... that error code means that you have a CD that's bad in the 6 disc changer.... If you're handy... you can take your radio out and manually remove the cd's and make sure that the 6 trays are aligned properly and not stuck together. (known issue) However, Lexus/Toyota does NOT repair ANY of their electrical components. They want you to pay for a NEW one at the tune of 800.00 PLUS installation... and they send the old one back to Japan and remove the CD's and mail them to you. (at no extra cost... as the service rep was telling me.. as to benefit feature me on the sale of the replacement unit.) Next be ready for the "Disc Read Error, Check Disc" on your navigation... lol.. it's a 2.10 motor that moves the lens that reads the DVD navigation CD.. and once again .. they don't replace or repair... that's a 4500.00 item plus installation.. GOTTA LOVE YOUR EXPENSIVE CAR NO? ;)

SOURCE: changing spark plugs
This is the 3.5L inline 5 cylinder engine. The spark plugs are at the top of the engine. They are covered by a hunk of plastic called the "Air Intake Resonator". Remove the plastic. Carefully pull the ignition coils from the spark plugs. Unlike most other cars. The Colorado has a coil on every plug. This boosts ignition power, but, every coil is expensive. Do not harm them.
