Having problems with your 2000 Toyota 4Runner ?

Changing the spark plugs on a 2000 forerunner

\015 OK, let me rephrase. How do you access the plugs? There is something that is covering it that connects to the air cleaner.\015 Posted / edited by AnonymousUser on : 18-11-2019

Answers :

The upper intake plenum...you will have to remove the plenum to access the spark plugs...usually you are able to unbolt the plenum only and disconnect the front connectors and/or vacuum lines. and tilt the plenum up and out of the way to access the plugs... take care when doing this you can damage the engine if not careful. make sure you get a new intake plenum gasket...as well as the valve cover gaskets...the rubber rings that seal the spark plug tubes from oil tend to leak causing a misfire. you already have to pull the plenum might as well do the valve cover gasket while you are so far in it.
