I just bought a 95 pathfinder 4x4. It has some issues that I am slowly working out. I suspect a right manifold leak, and I read this is pretty common. How difficult would that be to replace? I also have noise coming from my timing belt area in the front. I'm sure I can replace that, but is there anything I should be aware of before starting that project. The interior light will not come on when the door opens and I have to manually flip the switch on the roof. Thanks for any advice you can give. Feb. 3 2007, still has the manifold leak, timing belt noise, interior light switch problem, Now with a few new problems, It has to have a cv boot replacement, how difficult, and will a split boot kit work?, It gets horrible fuel mileage, and is lacking in power. It hesitates, and downshifts on the smallest of inclines. I just did a tune up, plugs, cap, rotor, fuel and air filter. It has a front end rattle that is driving me crazy, maybe shocks? Thanks for any help.
