I have a nissan altima 2006, and when i start it for the first time in the morning it accelerates on its own, it used to be just a little but over time its gotten worse, what could it be?

Start with the basics. Look for vacuum leaks. Do you have any dashboard lights on?

Unmetered air getting in to throttle body. A vacuum leak. The ECU does not 'know' that extra air is getting in and does not reduce the engine speed at IAC
Good morning B-mark. That was not there when I posted, but at least we agree
Good evening F.N. I'm going to give advice like that to more and more postings. BASICS. More often than not, after going through a long and technical explanation of what could be the problem the final solution is something like this. " Oh the battery was dead" or " The check engine light has been on since I bought it and now it wouldn't start what could be the problem?"
