I changed out the front bank of plugs on my 2002 Sienna with no problems. I can get to the back bank to get the clips off of the coils, but I can't get enough torque on my ratchet to loosen the plugs. I've read where others have had success getting the back row of plugs out without removing the plenum, but I can't understand how they could turn the ratchet. Has anyone done this that can give me some advice? I gather the V6 Camry is similar.
If I have to take off the plenum, I have the Haynes manual, but it leaves a lot to be desired in terms of its detail. Has anyone taken off the plenum? How does one releive pressure on the fuel system? I don't see where Haynes covers this.
Finally, I'm thinking of breaking down and buying the factory service manual. Is Toyota the only option?
Thanks.
