Honda Civic check engine light?

We bought my sister a used 2002 Honda Civic a couple weeks ago, and she loves it, but it didn't have a way to hook her iPhone into the radio. In my Trailblazer I have a cassette player where I put this little Cassette to iPhone adapter. She only has the factory AM/FM CD Player. I went on eBay and found a remote cassette player (a cassette player that plugs into the back of the factory radio and mounts where the storage bin is located under the radio). I purchased it as a Christmas gift, and installed it this weekend because she is out of town and I wanted to surprise her with it. Before I removed the radio I disconnected the battery, when I finished and put everything back together I reconnected the Battery and did all of the tests on the radio, like putting in the code, etc. And then I turned it on to park it where she had it and the check engine light is on! It was not on before I started. So I get the code reader and it says P1259: Vtec System Circuit Fault (Bank 1). What does that mean? It runs normally accept when it switches from 2nd gear to 3rd and 3rd gear to 4th it revs really loudly in between the switches (automatic).It has done that since like a week after we bought it. I'm getting worried about this car, I thought it was great, an 02 Honda with only 117000 miles, and now this only like 3 weeks after we buy it. Any help as to which parts I should replace to fix this would be great!

Added (1). I did not get the AUX adapter like you are speaking of because I'm 16 and I have to buy gifts for other people too and my summer job did not pay that well and it is $60 and the cassette player was only $25 and it sounds just as good. But I'm not asking if the cassette add on was better than an aux adapter, I'm asking if installing the radio could have thrown the code (which we have established didn't) and what I can do to fix the code. I'm also not looking for someone to be condescending and tell me how impossible it is to answer this question. If you lack the ability to answer this question, then please don't. Two people have given me input, which proves that while this is a tricky question, you could have just as easily recommended I see a mechanic without being condescending.

How to be more patient while waiting for iphone 5s?

Basically, sometime in January I'm getting a new 5s. But I'm getting so impatient and excited about it! It's because I've had the phone I have now since the start of 8th grade (I'm halfway through 10th now) and I was actually supposed to get an upgrade more than a year ago. My mom has been putting it off for a LONG time.

And before you say it, I'm not being spoiled. Whenever my mom would delay it before, I was fine with it, because my phone still worked, I had headphones for music, and I have a kindle anyway. But my headphones broke (at least I had them for 3 years) and my phone is seriously jacked (it routinely calls the police by accident). Since it's more a a burden at this point than anything, I need a new one, and my mom promised my the 5s for being so patient before.

But now that I really need it and I know that it's coming, I'm too excited about it. All I've been doing recently is googling things on the net about, searching for accessories, talking about how cool it's gonna be, and more; it's getting a little obsessive, and I've still get at least 5 weeks before it gets here.

My question is, how can I calm myself down? If it's bad now, I can't imagine how it'll be by mid-January (I'm already running out of articles!)

(P.S., I can't just not think about it, because I do every time I look at or have to use my current phone).

Added (1). @Retired RN: I get straight A's. My grades couldn't be any better no matter what. That's partly why my mom wants to reward me.

@saraimay75: There aren't any volunteer shelters in my area, and I do theater and marching band, so I don't have time for it anyway.

How to organize my pictures after backing up my iphone 5c?

Okay so I used to have the iphone four. Just recently I have gotten and iphone 5c. Before I got the new phone I backed up my old one with itunes. And then when I got my new iphone I restored it with everything from my old phone. However, my new phone has less storage than my old iphone. So I was just going to remove all my old pictures from my old iphone. But it won't let me simply delete the pictures and I can find a way to do it myself. So How can I get rid of my old pictures from my iphone 4 that are now on my new iphone 5c?

Is 16GB memory enough for an iPhone 5s?

I know, iOS 7 uses about 2-3, but is the remaining 13 enough? I want to have about a 100 songs, no movies. Maybe 50 average size apps, including games (not console size, but average games). How much data and cache will be used by these apps? Can the device slow down due to low memory?
