My Nissan drivers door won’t open from the inside or outside does anyone know how to get the door open so I can take the panel off

I don't know why my pathfinder is hard to start like this missing fire or something like that

I've got a line on a Bush Bar off a '95 Pathfinder for fairly cheap and in good shape. So I'm wondering if it'll fit my '97 Hardbody 4WD. Any thoughts?

I have a 02 frontier and when I start to move the truck goes very slow and almost kills. Once I hit about 20mph it stats to move normal. When driving I am at almost 4k rpms and doing about 55-60mph. I was told the clutches may be going out. I want a second answer before I start taking truck...

Car runs perfect for a few miles. Then the valves will get very loud, but it does not lose power.. I can turn car off and wait about 15 minutes and start it back up. It will be quite and running perfect. The I can drive it again and it starts doing the same thing. Please help.
