Just replaced plugs, wires, pcv, air filter and fuel filter. Also replaced a faulty vacuum elbow that was leaking causing a lean fuel fault. All this morning

Now it will stall every now and then when coming to a stop, rpms drop really low and it stalls.

Do I need to do something to get air out of the fuel line after replacing the filter or is there something else? this is the first tune up after 60k miles on a 99 with the 4.2

 

When you come to a stop, and it almost stalls, but doesn't, does it recover and idle normally, or does it continue to idle low and rough until you take off again?

 

If it doesnt stall the idle returns to normal after a minute

 

Double check your vacuum connections.

 

yes I did, didn't see anything but I suppose when I changed the PCV valve I could have pulled too hard to get the old one off and it is really hard to see back there. i also replaced that elbow that comes down out of the throttle body, where does the other end connect too, I can't see it either.
