Was parked for a week and when I started the car and put in reverse it made a sound and it feels like I run over something. Feels like it's not in gear and it made it difficult to move in reverse but after it warmed up it's gone. But it did it again after it was parked for 2 days. Same problem driving in reverse. I can't really determine what is wrong with my car. Pls help!

Has the check engine light come on? Has it ever done this before sitting for a week? Does it do it all the time?

Engine light is on but when we did the diagnostic the code calls for too lean of gas as we've been using the regular unleaded and this is the first time that this ever happened.

It could be a problem with the trans control module (TCM). Also, the lean mixture is most likely a vacuum leak. What I suggest for the trans is to have that computer scanned by a trans shop.

Let me know what you find.
