I have recently replace my MAF sensor as well as an engine coil, but I am still experiencing many other issues. My check engine light is back on and the first code that came up was related to the catalytic converter. Every morning or when my car is parked for a long period of time the car shakes when back up and then cuts off, and if it doesn't cut off when i go to drive the car will not accelerate and when it does the rpms jump for a little bit. The second thing is my car makes almost like a clicking (hard to describe) noise only when I back up. The third thing is my gear shift about a year ago just stopped moving so I could no longer put it in gear so I had to use the override button and I have been using it ever since no one can seem to tell me what the problem is and the dealer is sooooo expensive. I know it is not the break light or fuse, that is working just fine. Lastly for awhile my car was blowing a lot of fuses it hasn't done it recently (knock on wood) and there is almost like a burning smell that comes out of the vents mostly in the winter I don't know if the two are related?? Wheeew that was a lot...I hope someone can give me some answers to some of my questions??????
