I have a 99 Pathfinder. Has run great up til about six months ago. Now, on acceleration, it sounds like a marble sack. It has little power. I have been trying to troubleshoot it...observing under what conditions this occurs. Here is what I have come up with.
It happens on acceleration.
It does not occur when the engine is cold. Need to give it 10 minutes or so.
It is absolutely terrible when I have little gasoline in the tank. The more gasoline in the tank the better it runs.
I'm thinking there may be several factors contributing to the problem. One may be that the tank has water and other contaminants and when the tank is full these rise to the top. When the tank is low these are on the bottom and enter the engine.
Any mechanics out there care to speculate? I figure that is DR related as water in gasoline is a known problem here.
