I was curious as to what number that guage showed when you were hearing the noise and going 30 MPH. Did the noise come from in front or from the rear? Any warning lights on the dash?
The noise came from the front, but there was no lights on the dash board, which is unusual. I am going to check the numbers. OK, the car's speedometer doesn't show more than 10-15 ml, and the RPM is between 1 and 1.5
Its very hard to diagnose what you have going on with limited information. I can tell you that if when you hit the brakes you hear a noise or feel a grinding you are probably metal to metal and need immediate attention to your brakes. If you are leaking coolant(the green stuff in the bottle) You also should have it looked at. As for the reason you cannot accelerate past 15MPH There are multiple reasons this could happen. We would need to be able to distinguish the part of the drivetrain that is failing. Engine or transmission. From what you are relating it sounds like its engine related. Im not sure if the noise is connected, I would need to have a better Idea of where the noise was comming from. The botXXXXX XXXXXne is that you really need a professional to look at your vehicle and assess its condition. If you call AAA you can find shops that are reputable. You may call around and see if you can get one to give you afree estimate or at least give your car a quick once over to provide you with an idea of whats wrong. Please let me know if I can further help.
Hope your car gets better.
