My first post to these forums.... love my maxima and wanted to involve myself in the community!

I bought a nice 2011 Nissan Maxima, 48,192 miles, runs great.
We needed to get an oil change quickly, as the seller was quite past the time required.
On my mistake, I thought I understood that the owner had placed Conventional Oil in the car, and I proceeded with the trend. To my mistake and knowledge, he always had put Pure Synthetic Oil in the car.
My solenoid has been giving error codes, and my car is running very rich, wasting lots of gas. During some accelerations, it can get jerky.
Could this be due to the change from synthetic to conventional? I've looked around and asked friends and they say that the solenoid could be clogged and a thorough motor flush can fix? What do you think?
Thank you!

Dude what? First of all, the guy you bought it from not changing oil at the right interval, sounds like he just F'ed you over with a poorly maintained car. An oil change wouldn't cause these kinds of problems my friend, someone is blowing a lot of smoke. One thing I've heard, and appreciate the previous poster for his links, but one thing I've heard is that once a car has been using conventional oil for extended miles, the benefit of switching to synthetic is minimized. In that you're essentially wasting your money switching to synthetic later in life. That said, Oil is oil for the most part. Just change it at the right interval, use the proper spec based on the manufacture, and you're good. BTW, what solenoid are you talking about? And who told you it was the oil change that is fouling things up??? I'd loose them as an advisor of anything automotive.

Unless you mean Mass Airflow Sensor, which is in the intake past the air filter. Again, nothing to do with motor oil...
