  1. First you have to know how to open the windshield rain gutter which contains the wiper's motor so you need to take out the wiper motor out as well. Remove engine stable bar (see SKETCH 1) out too. (See picture below) OPEN THROTTLE (see sketch 2) Open (1) #12 screws behind throttle with wrench not socket (it is at vertical support bar), (see D detail in sketch 2) Open(1) #10 screws behind throttle which it hold electric bundle to throttle body (see B detail), (Note: you don't have to put this one back, it is hard to open and without this screw it is still strong) Open (3) #14 (or, #12?) nuts which tight throttle to upper manifold, (see sketch 2) PULL THROTTLE to the right and off from upper manifold, use some cord to tight it to somewhere so it won't dance around (throttle now still tight to some hoses and some electric cords) Careful take out throttle metal gasket, use it as simple for buying the new one (you have to replace it with a new one every time you open this), ( gasket beat position ) OPEN UPPER MANIFOLD (see sketch 2) Open (1) #10 screw at gas hose clamp which locate at left side of upper manifold Open PCV valve At bottom of engine, open (1) #14 screw at vertical support bar, the one support upper manifold (see picture) Attop Manifold, open (2) #14 screws, the one locate at 2 front ends, (see sketch 2) At top Manifold, open (2) HEX screws, they locate at front center, (see sketch 2) Lift upper manifold a little, slidely tilt back side up and to the left. While you hold it there. Open (1) #14 screws at vertical support bar (You may have to use a very short socket wrench to open this bolt _ see picture). And open (1) #10 screw which tight ground electric to upper manifold body Take out upper manifold body AND CHANGE SPARK PLUG
