My Ride: 1999 BMW e46
Arrow BMW Engine video - Wtts going on with my Car??

I have just purchased a 1999 BMW 323i 4dr Automatic

A couple of minor problems have already been fixed
(window regulators, headliner, Final Stage Unit, Mass Air Flow sensor)

After replacing my MAF sensor today I had my car diaginosed at AutoZone,
9 out of the 10 original codes have gone away..... only 1 remains.

P1770 - CAN Torque Interface

I've read on similar post, that P1770 deals with transmission sensors, or could be a result of a bad MAF sensor. But since I have just replaced my MAF I am
trying to decide what sensor/part I should replace next.

I have recorded a video showing my engine problem.
If anyone can detect the issuse PLEASE let me know.

Im scheduled at the BMW dealership next week,
$140 (before tax) just to have them scan my car and
pin point the problem area. . . . .

In the video, i stop the car in drive, and show it revving up, then place
the car in park and show it idling steady, I also pop the hood and show you around the engine.

Thank you to all who have invested an interest in my issue.

I love my BMW, this will be my 3rd one, and want to maintain
it to prevent future MAJOR problems from occurring
