Question about 1989 Ford Bronco
Is your check engine light on? Could be mass air flow sensor, or throttle positioning sensor but your check engine light would be on if thats the case. It could also be the humidity and not the actual temperature, this is a system of a worn coil pack, or condensor in distributor (these wouldnt turn the check engine light on). Trouble is there is an enormous amount of could be's. I have heard of this happening with a cracked canister in fuel pump, also if their are other minor power related issues it could be a dying alternator, it would slow the fan speed. First thing I would try if you have no check engine codes to work with is turn the heat on full blast into the cabin and see if it runs longer under this condition. (this displaces some of the heat under the hood). Hope this makes sense and gives you a starting point.

Like Laurie Mack said. It is the inertia switch below the glove box. Here is some funny information. DON'T change the fuel pump first. Interesting fact: I bought the new inertia switch from Ford and the install instructions that came with it said to install the switch in the protected area to the right where the fuses are. It is like Ford knows it was a dumb place to put the inertia switch, but they won't let you know until after you buy a new one. I have read at least 20 other people on here that had the same problem I just had.

you need a new fuel pump. There was a program to pay for this for 10 years I think for some 2000-01 Foucs. Here's what the letter from Ford says: December 2003 Program 03N01 "Attached is a letter announcing the details of a no-charge program Ford Motor Company will be conducting concerning your vehicle's fuel pump. We have found some 2000-01 Ford Focus vehicles may experience symptoms of engine hesitation, loss of power, surging and other similar symptoms ...... as a rsult of progressive contamination of the fuel pump filters." (in the fuel pump). You may reduce the liklihood of the symptoms occurring by kee[ing the tank at least half full. My recollection is the program was good for 10 years. Ask your local Ford Dealer if your car is eligible for this program.

The bronco II was discontinued over 20 years ago so you are driving an antique. Any number of things could thus be wrong with it, most of which will cost more than its value to repair. Every part on every car ever made will fail due to age and/or use. In any event I had one, V-6 type, long ago and they had bad distributors and were prone to vacuum leaks. So I would first put some thought into finding and eliminating any potential vacuum leaks, the brake booster hose frequently went bad on mine. You can't find these in junkyards anymore, but you may be able to find a new distributor on eBaY.
