general problems of the 2002 Nissan Maxima

When I first purchased this car I had immediate problems with the power steering fluid. The check engine light has remained on the entire time. But the car was hemorrhaging fluid, groaning, whining, and my steering was becoming extremely loose. I call the dealer that sold me the car, because I dropped 4 grand on what seemed like a nice vehicle with under 100k on it. Well, I bought the car right off the lot and they refused to repair it. Cool, I respect that. If the inspection reports and other papers are clearly falsified. It couldn't have passed inspection under normal situations. But since the dealer owns their own shop, they could slap stickers on busted vehicles and send them off to be sold. Eventually they do me " a favor" by replacing the power steering actuator/pump hoses & did work on towards a dtc code p0550. They give me that favor by charging me only for the parts, no labor. Totally cool, if work was done. It still has the same electrical tape in areas that was "fixed". They clear my codes and off I go. Engine light cuts on again and I'm having the same issues. My power steering fluid looks like it's boiling or bubbling as well. Still getting the p0550 code as my main dtc. Except now, I'm having major problems and my car has been sitting for a month. Not sure if the leaky fluid corroded components from before. As of now I'm throwing dtcs for p0171, p0305, p0550 (twice), believe I have a vacuum leak, my exhaust system is damaged internally from the misfire codes and has also broken apart near the rear muffler, among other pending codes. Lastly, I was coming home from work and my car completely loses power and bogs waaaay down. Engine light is flashing and I have no control or power. I limp home, park the car, and haven't drove it since other than for test drives. After countless repairs for the same issues, among new repairs and issues I'm broke. Issues started on 3/24 through 12/21 not had this car for a year and it's been a constant pain ever since.

Car starts but dies down after a few miles.

2002 Nissan Maxima. Two incidents of the electronic throttle control actuator failing. First failure in 2003 (odometer reading 10460) and another in 2009 (odometer reading 47199). When this unit fails, the vehicle may lose power as it happened to me in 2003 when I couldn't drive more than 15 mph. Both times repaired by Nissan service department. I have repair paperwork if needed. I have contacted Nissan about the problem and they have set up a file number for my notification.
