Engine Mechanical problem
2001 Dodge Durango V8 Four Wheel Drive Automatic 101000 miles
When my car is in drive with or without pressing gas it makes a rattling or popping type sound when it is moving. When it is in park or neutral and you press down on gas everything sounds fine. I have taken it for repairs and was told bad gas. The sounds seems to be getting louder and more frequent. I changed the gas and have been using higher octane for the last 2 months.
