Hey all. I can't get the Phoenix to move on anything higher than idle. In Park/Neutral I can step on the gas all day and it'll be happy to rev, but in Drive if I try to step on the gas it wants to die. Transmission load problem? The Transmission leaked all the fluid out over the last few months so I had to bring it back to the proper level. Ran and drove fine the day I did that (Saturday), but yesterday (Monday) it was doing as described. Only other thing I did that Saturday was change the oil/filter, but like I said, she ran top on Saturday.

Change the gas filter.

Agree on the filter change.  If the fuel that's in it has been sitting a long time, you might want to drain that also.  Alcohol blended fuels have a strong affinity for moisture.  Is you car carbureted or injected?
