I have a 89' bronco 2 with a 2.9 and im trying to bring it back life after is been in storage due to deployment. my problem is, wont fire up without feathering the throttle and will not idle . im looking for possible idea on where to look to get it back on the road.
already looked into:
- fuel pump/filter
-plugs/ wires / cap, rotor

sounds like a problem with the idle air is the thing bolted to the passenger side of the intake manifold. try taking it off and looking inside while someone cycles the key on and off to see if it moves. if not try blasting it out with carburetor cleanerand move the valve a little with your finger to try to break it loose in case it's stuck.

I had a similar issue and it ended up being the Air Charge Temp Sensor, about $20, on the passenger side of the upper intake manifold. Sensor was telling the engine it was below zero outside and the engine was guzzling gas to compensate, which also caused it to stutter and stall out when I first started it up and putting it into gear.

Simple quick cheap fix, might be worth a shot.
