SOURCE: how to change spark plugs on 2005 acura tl

Hi,

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.

I have helped many Honda/Acura owners on this issue. Many mechanics will replace many parts prior to solving this problem, which then creates unnecessary repairs and spending. So here is my diagnosis: Notice if your speedometer drops to zero when your engine dies while driving. If this happens its your ignition switch failing. Ignition switches in Honda/Acura vehicles years 97-02 encounter faulty or shorted internal contacts. This causes premateur electrical failure to vital engine electrical parts, causing vehicle to stall intermittedly. A recall has been in place since 2002, approximately 1.3mil vehicles are affected, call your local honda/acura dealer for info and possible free repair or replace the ignition switch yourself. Hopefully my info helps you!!

I doubt they did anymore damage but i`ll bet that the engine was damaged from the training going out such as valve guides and seals and carbon build up on plugs ETC.
