Question about Ford Bronco II
My bronco had been stalling, but everytime I go to troubleshoot it, it works fine. As I was tinkering on it today found a vacuum leak at the pcv valve, I cover the inlet with my finger and the engine runs a whole lot smoother, but cannot find where the vacuum hose that goes to it is at. do I have the wrong pcv valve or missing hose?
You have the correct pcv, the second port is not always used and the port that isn't used is simply plugged off. New pcv valves even come equipped with the block off plug.

SOURCE: pcv valve
The positive Crank Case Ventilation (PCV) is coming from the intake manifold and usually goes to the Valve cover On that year it could be in the back of on the side of the Rocker covers ( Valve Cover) find the Vacuum line coming out of your intake and follow it, It should lead you to the Pcv

If it is the same engine design as the F-150 ( think the '98 was still the 2V V-8 ) it could be the IAC ( Idle Air Control ) is gummed up.
The F-150 it is mounted on the back of the Throttle Body ( have to take off the plastic throttle body cover to see it ), held on with 2 bolts with 8mm heads ( could be 9mm ??).
Worth taking a look, also take a look at the VAC line to the back of the throttle body, and check that the IAC connector did not get unplugged or the wires damaged from the other vac line change

You have the wrong type hose on the pcv valvle. It isn't vacuum hose.
