1989 Bronco Ignition Problem
I have a 1989 full-size Ford Bronco (F-150) with a 4.9 liter in-line six, manual transmission (4wd) with A/C. I have owned it for about six years, and a few months ago it began to have very poor power in the lower RPMs. It feels like the engine is missing and trying to die, and the Ford dealership could not figure out what is wrong with it. They replaced my starter, and I had another shop do a tune-up, but it still has the problem. I replaced the ignition module, but that did not solve it either.
I was wondering if there might be something wrong with the engine computer. I thought about just replacing it, since that is within my abilities and is cheaper than taking it to the shop again, but I cannot find the correct one online. There seem to be 20 or so different ones for my truck, and none of them have a part number that is specific to the markings on mine:
E8TF2C018-AA A
0469173CIV

If you know the answer, I would sure love to hear from you. If you know someone who might know the answer, I would certainly appreciate if you would redirect this to them. Thanks.

There are SO MANY things that can cause your problems. Do a search and you will find tons of info. It could be any of the following plus more that I can't think of; fuel filter, fuel pressure regulator, plugs, wires, distributor and or cap, rotor, catalytic convertor, EEC module etc... It is relatively cheap and easy to replace plugs, wires, distributor cap and rotor if they have not already been replaced ?
Computers do go bad but they are not that likely to do so.
Good luck,

Get a code reader for your eng. Ebay for $25. Go to fordfuelinjection.com and read up on the info on that site. Once you pull the codes, you should be able to trouble shoot the problem without replacing parts that do not need replacing.
