Cruiser has 294k miles on it. Hardly drove it this year Planning a big trip for next year through the San Juan mtns but might have a bit of a chore for the winter months.
Recently I have noticed more of a vibration while driving. Initially thought it might have been something in the driveline but then it seemed like the beginnings of a misfire (never driven a car with a misfire, just what I suspected). Shop ran a compression test and found 148-150 on all but cylinder #1 which had 110. Before I pull it in the garage and tear the motor out and rebuild the damn thing.... here are the symptoms. Please let me know if you would recommend running any other tests or have ideas as to what else it might be.
The roughness or vibration is only present when accelerating, and gets stronger with speed.
When I let off the gas, it coasts just fine without any roughness.
In neutral, the engine revs smooth.
Please let me know what you think, thanks!
