So my Bronco needed a little extra push this morning to get started, and I left it running for about 15 mins to heat up.

When I went to take off, I push a little more gas and then the engine died.

The air filter is taking cold air in directly d, even though the engine is so hot. This has happened to me on old Ford before, and the way I got around that then, was by forcing the air intake to come over the exhaust manifold to heat it up. The problem Im having here though, is that there appears to be no tubing for air intake never mind something that runs in the direction of the exhaust manifold. I dunno if this is something that is usally on the Bronco and is simply missing or if there never was such a thing. I cant even find a picture of a complete engine to even check. My Haynes manual doesnt appear to show anything but it also only shows partial drawings so its not suprise.

Either way, if anyone has an idea that could help or solve this please let me know. I would hate to have to retire my B2 for the rest of the winter.....

Your air cleaner should have a flange on the horn that drops down towords the driver's side exhaust manifold. The manifold has a piece on it that directs the air from the manifold through a piece of duct to the air filter. Your's is probably missing the piece that is screwed/bolted to the manifold and of course the air duct. When it's cold the butterfly on the horn of the air filter can closes so that it pulls the heated air from the exhaust manifold. I'll try to get a pic of mine. Mine doesn't have the duct in place though.

that sounds exactly like the bit I am missing - I had the same solution on the other older fords I drove. My thoughts are I could probably pick one up at the junk yard. Failing that, does anyone have any creative ideas?

On one of my old fords I used to drive, I ended up permenantly opening the pipe directly to the exhaust manifold. I dont know if it had been jammed or whatever, but it only every ran smoothly with it like that during winter.

Thanks again for your help...

Any of the carburated 2.8 liter engines should work for you. They were also in the mustangs I believe. You may just be able to dangle a piece of duct from the flange on the horn to the manifold and put some weight there to keep it in the warm air area.. maybe welding magnets from Harbor Freight?
