[DeTomaso] Engine help needed - I've got gas! (or my car does....)

[Asa Jay Laughton]

Also, make sure the engine is good and hot (not overheating).  Take it 
for a good long spirited drive and then immediately have the emissions 
tested.  If the line is too long... come back again later.  You get 
better test results when it's been running good and hot for a while.
