2005 Subaru Legacy GT 5MT
Having an issue where my Subaru feels like I'm driving over a constant rumble strip. Thought it may have been a spark plug issue but changed those out and still not fixed.
Here are the symptoms:
- Most noticeable during acceleration/deceleration (applying/letting off the gas) and primarily on non-hilly roads, at higher speeds
- Is the absolute worst when on cruise control coasting on a relatively flat surface at 50-70 mph
- Not noticeable in neutral while coasting or while going downhill
