You're welcome 
One other thing, though- right when you get to the LL, you need to figure out if there's OLL parity before you do anything else, because if you wait until the very last step to solve the parity, you'll disturb the orientation of your corners, and you'll have to essentially redo the LL unnecessarily.

if you want to try another algs, just search about 4x4 parities, you can also search for videos that show you how to fix it

4x4 solve help
when i solve the last 2 4x4 edges and the centres are misaligned, i solve the edges but then the centres remain misaligned. I cant realign them because that would destroy the edges. All the edges are solved so i dont have any "free spots" What do i do. And can someone further explain parity. When do i apply oll parity and when do i apply pll parity and what do these parities do. I just got a maru 4x4 and i have one question how do i open the maru lube bottle and how do i lube my maru 4x4

I see that you have a case where the two dedges are across from each other. Hold the pairs in front of you horizontally. Do
Dw R F' U R' F Dw'
You apply the OLL pairty when the dedges are flipped.
You apply the PLL parity when you see it.
You open the lube bottle by twisting it........
To lube your maru, just put two small drops inside. Then work it in.

Ok thanks for eceryting but you didn't understand my first question. Idont need an alg. This is my situation. I paired up all the edges I'm about to begin 3x3 step except 4 of the centres are misaligned. I can't realign them because that woul destroy the edge pairs. What do I do

First you need to know that the color pattern when looking at the white with blue on top means that red is on your right, if it is not, than do this (still looking at the white face)
r2 L2 r2
then make sure the color that needs to go on the left side is on the top of both of the middles on your right and left side. Example:
Right middle: RR Left middle: RR
..................OO.................OO
Then do the algorithm r2 L2 r2 again
If you have done this correctly than the edges should still be together, red is on your right, and orange on your left.

If your centers are messed up, then just finish solving them and then fix the edges.

actually, I can do it.
so, if they're adjacent, put the ones needed to be switched on the front and top.
Do Rw U2 Rw' Lw' U2 Lw
For opposite centres needed to be switched, replace all Rw and Lw moves with Rw2 and Lw2 respectively.
This should be done before starting the 3x3 part

Ok I'm trying to try once more than I am posting a picture. My centres are correct I know my colour scheme inside out the problem is that I need to do a Uw to correct the centres but I can't because that ruins the edges. I have to revert the centres. Please help I'll post a picture in a few hours.

Solve the centers, leaving you with four unsolved edges. From here you can do two-pairing once, which will then leave you with two unsolved edges. Place these two edges at FL and FR with each edge parallel to its partner, like this:
O O O O
X O O X
Y O O Y
O O O O
Then do this alg: Uw' R U R' F R' F' R Uw
O O O O
X O O X
Y O O Y
O O O O
Then do this alg: Uw' R U R' F R' F' R Uw

ok guys i found the problem im stupid. I put the centres in the wrong spot...

4x4 Parity help and such
I just watched that mind-boggling 6x6 solve and I saw he was using double layer turns. I knew that you could do it and that for center solving it was much faster than doing a single slice move in the middle of the cube. I'm getting a 4x4 this weekend and I was wondering if you could use double layer turns on that as well. I was under the impression that you could but then I watched some solve videos like Feliks's WR Single and I noticed that no double layer turns were used. I may have just been the videos I saw or is it not efficient to use double layer turns? I also thought that OLL Parity cases and all that was solved fastest using double layer turns or a 2-gen algorithm but I don't know too much about big cubes.
So basically
Can double layer turns be used on a 4x4 cube while solving parities and centers or is that just on 5x5's and larger cubes?
Does the term "parity" refer to all awkward cubie orientations that prevent the cube from being solved? I thought it was just when you have an edge group that is flipped so that the top color is on the front and the front color is on the top. But are there more parities than that one?
I know I've got other questions but they're aren't really coming to mind right now but I'm sure I'll remember them as I get some responses

Um.. its hard to post something useful. Everyone uses double layer turns, it might look like someone is using a single layer (especially faz). It is fastest to use whatever is the most useful. Many people use OLL parity with double layer turns. PLL parity alg seems like you are turning 1 layer, but the way I perform is much similar to an M slice on a 3x3 like R2' r2, is a slice turn.
For parities, that is a very simple way of thinking about it. I would give a response, but it won't really make much sense anyway... there is OLL parity, which is what you are thinking about. But there is also a PLL parity that leaves 2 edges flipped. Where the orientation is correct, but you are left with a cycle of 2 edges, which is impossible on a 3x3. Also, somes say there is an edge pairing parity (I'm not sure if that is a true parity on 4x4, but there are many cases for last 2 edge groups on 5x5, some of which are true parity). If you use 3x3 beginner method where you orient and permute edges, permute corners, then orient corners, you can come across a different PLL parity of 2 corner swap.
Also, in future, please use the search function as there are countless threads on these same question

I appreciate the help but I did use the search function and didn't find anything useful, I don't doubt that they exist but I couldn't find them.
Is there anyplace where we have a collection of 4x4 algorithms? We've got a huge compilation of 3x3 algs for Fridrich but I haven't found a single place that has a collection of edge pairing algorithms or for the parities.
If we don't have big cube algorithm pages on the wiki we should definitely make one. We've got them all written down on the wiki an a thread here was started recently. Everybody puts a lot of emphasis on 3x3 Fridrich and all the other resources on other methods have just been floating around with no real organization.

I always go to Stefan's site when I forget 4x4/5x5 parity algs.
As for parity, I think Ryan Heiss gives a very nice explanation here. For many people, however, it's enough to think parity = bad. As has been said earlier, parity can present itself in two ways (referred to as OLL parity - a single Dedge flip - and PLL parity - A two cycle of Dedges -) on the 4x4, and you'll come across another on the 5x5.
Think of a parity issue as a case which would be illegal on a standard 3x3, and you'll be fine.

I'm not positive, but I think if you are careful about what you are doing, you can avoid parity on a 5x5. If you can't, you can use the 4x4 OLL Parity to fix it right up (so you don't have to learn anything extra for the 5x5).
