Recently purchased the  PMDG 737 8900 FSX Steam. Plane works except whenever I end a flight then begin another flight the airplane gets weird with these two occurrences.

The plane bounces slightly on the runway as if the wheels were impacting on a hard landing. The next one is sometimes the gauges in the cockpit spawn black screen. If I exit FSX Steam and then start up the same flight everything is fine. The only problem is that is not what I want to do every time. 

Restart the sim before the next flight. To avoid restarting the sim you can try loading a simple stock plane and then load the PMDG but best to restart the sim between flights.

Please ensure that you read the Intro Manual. It recommends against doing this, specifically.

Full names in the forum, please - first and last.

I bought this fantastic aircraft knowing it was what It is a better 737 than the iFly (which is a great aircraft) but it has way to many issues so far. I hope I'll eventually get these issues ironed out.

Well after hours of reading everything i could find on this I am stumped. From what i have read PMDG 737 8900 NGX in Steam (or just FSX) don't play together well at all. I can run a flight but if I end mission to correct something and re-enter the same airport the PMDG aircraft causes FSX Steam to either crash to desktop or causes a loading of the cockpit gauges being blank, I have to load up a different aircraft other than the PMDG then go back to the PMDG for it to work. I have FSUIPC4 installed and all other payware study level commercial aircraft work without so much as a hiccup.

I really don't think there is a fix out there from what I have seen. Maybe somebody who has more experience with FSX and the PMDG 737 can help.

Good answer.

Good advice.

Rules.

 

Think of it a bit differently. They packed in a few things that push the limits and mean you lose a bit of functionality around restarting flights. Not a deal breaker.

Yes, that is exactly correct. As Kyle mentioned, the introduction manual covers this very thing. You cannot and must not reload a PMDG aircraft when that aircraft is already loaded. Doing so will make the simulator unstable. You can either load another (default) aircraft, then go back to the PMDG, or exit the sim completely, then restart it and load the PMDG plane.

This is not limited to PMDG aircraft. Other highly complex FSX/P3D add-on aircraft can malfunction in a variety of ways if you try to load them twice in one sim session.
