HI i have a 1998 Camry v6 XLE and i have a engine misfire on 1 and 4. and so my car feels like its starting to slow down and the throttle isnt as responsive as it used to and i could feel the car shake/bogg a little. So i want to change all the spark plugs myself. I know the 3 spark plugs in the front of the car are easy to replace but i was wondering how to get to the back of the engine to replace the other 3 spark plugs since there is no room in the back to work on. and also which cylinder are 1 and 4?

 

if you are unable to reach from the top........well, you'll have to reach from the bottom. this is going to be a pain in the @zz because you'll have no leverage while playing on your back. a lift would be good for this, so you can stand up and work. i would also buy a new set of plug wires, because you are going to break them. also, be sure to buy a tube of "die-electric" compound. its "grease" of sorts that you put into the spark plug boots, to make the next replacement easier. now typically, number one cylinder is the cylinder, when you look at the engine, is "pushed" forward a bit from the other cylinder head. in other words, looks closer to the engine pulleys, and the other head is slightly pushed back from the pulleys.
