To change spark plugs on a 1994 Toyota Camry, remove the black shafts. The spark plugs are down the four holes. Use a socket set with extension to reach the spark plugs. Replace old spark plugs with new ones.
I suspect you have V6. If it is the case, you will have to remove intake manifold. There is no other way to replace it.
Disconnect the battery, remove the spark plug cables and boots, and remove the old spark plugs. Next, put in the new spark plugs, replace the cables and boots, and reconnect the battery.
How do you change spark plugs in a 6 cly Toyota Camry?
Get pre gapped plugs from dealer (irridum not platinum remove engine cowling remove coil wire remove old plug replace with new plug replace coil wire and cowling
There should be 2 access plugs on each side in the trunk. Remove the bolts and slide the bumper out. Maybe a foot in from each side.
You need to replace the EGR valve. Make sure to replace the plugs too after that.
Four or six? For both engines you have to take the plastic engine cover off. The 4 should be fairly easy. Remove the plug ignitors and remove the plugs. Engine cold. For the six,you have to remove the air inlet plenum/throttle body assembly to get to the back plugs ,although I have seen several entries on the Toyota Nation Camry forum where members say they have removed the rear plugs without taking the plenum off.New plugs need to be torqued. Use a very small amount of anti-seize on each plug.
generally on a Toyota 3.0 either in a Camry or an Avalon you need to remove the upper intake- also known as the plenium- to gain access to the back spark plugs. You will need to make sure that you have a new gasket for the plenium to avoid any vac. leaks
