How do i change the spark plugs on a 1987 toyota supra

SOURCE: Need specific instructions on how to remove the air "intake"

I have this same car and this is how I do it. You will be removing the throttle body. Before starting, make sure the engine is cool. ( There are two coolant lines to the throttle body to help heat it up and keep it from icing in cold weather. You can elect to drain some of the coolant out of the radiator or just keep some rags handy under the lines when you disconnect them. Some coolant is going to drip either way---less will drip if you drain the radiator halfway before starting. )

Begin by removing the black air intake "elbow" from the throttle body at one end and the air flow meter at the other end. Label the three vacuum lines on top of the throttle body and push them off of their respective nipples with a flat blade screwdriver. They may tear if you pull them off. Next, disconnect the electrical connector from the throttle position sensor on the front of the throttle body by using a very small flat blade screwdriver and pushing on the two ends (one at a time) of the wire spring clip while gently pulling on the connector. Be gentle, the plastic on the connector is old and brittle.

Next, push off the end of the large engine breather tube next to the Throttle position sensor on the front of the throttle body. ( Use pliers to slide back the retaining clip if one is there.) Do the same to the PCV hose on the back of the throttle body. Now remove the medium sized coolant hoses from the throttle body. use rags to catch the small amount of coolant released when these are disconnected.

Push the throttle rod off of its ball stud on the back of the throttle body. You may have to pry a bit with a screwdriver to get it to come off. Remove the two black metal brackets on the passenger side of the engine holding the throttle body. Remove the brackets entirely not just the bolts on the throttle body.

Now you can access the four bolts that hold the throttle body to the air intake plenum. They are 12mm and you'll need an extension to get your socket into the deep wells where the head of the bolts are. The throttle body should come out easily. There is a metal gasket between the throttle body and the air plenum that can be reused. Once you get the throttle body out of the way, you can get to those middle plugs. If you have problems, write a comment on this thread and I'll check back later to help.

open hood and remove cap to mater cylinder reservoir
using special tool (or C-clamp and something to protect piston) push the piston back into the caliper fully.

fit caliper on the rotor
Secure caliper to wheel with bolts
replace wheel
remove jack stand
remove jack
tighten lugs on wheel
replace hubcap

poss bad earth, check ecu supply when then cranking. if not you need an oscilliscope to see what is up with signal on crank sensor, some vehicles power cable is so close the noise from it wipes the signal same as a bad starter it interfers with the signal, (noise is the magnetic fields)
