I'm trying to replace my Van's spark plugs and I was able to replace 1,5,6,7 plugs but I'm having a really tough time on the passenger side. I can't seem to figure out how to get to those plugs especially from inside. Any tips? Surely I'm not the only one horrified of the experience. Help!

 

We always try to find some way to blow out any grit from the spark plug holes before removing them. Use a turkey blaster if you have to.
Usually, with the doghouse removed, you can gain access to the plugs at the rear of the engine. If you find it too difficult to get to the plugs on the pass side, I have managed to make it somewhat easier by removing the battery. If you do that , expect the computer to act differently until it relearns your driving habits.
