Changing spark plugs for the first time

[wardak33]

Just rolled to 125,000 and its due for an oil change, so i thought that i would throw in a set of new spark plugs. i looked at the engine and tried to figure out how to take them out in the first place. second, how do i get to the ones that are hidden under the throttlebody? is there something special i have to do? do i use a certain kind of plugs (irdium, platinum, etc.)? just wanted to know what the procedure was to replace the plugs...thanks

Take the ducting off for access, use Delco plats or Iridiums.
