Tonight, i was driving around in my B2 when i started to notice a sound coming from the engine bay, it was a ticking sound that i have never heard before... When i tried to give it gas, i had little to no power for almost 2miles than all of a sudden i had power again, and the sound was still there.
At first i thought it could possibly be my Cat's being clogged which is making it run this way, but the more i think about it the more im really unsure as to what could be wrong.
thus far , i have changed the oil/filter , plugs/wires cap/rotor, cleaned and installed a new tb gasket, Befor my oil change,also installed a new air filter . I ran seafoam trough the engine, in hope to clean out any carbon build up from it sitting or the fact of it's age.
this is my only means of transportation so if somone has any idea please give me other things to look at, a friend told me that it may be a bent or stuck push rod .... But that is the only other thing that i may look into.

Re: 1986 Ford bronco 2 running issue
Coil. It sounds to me like its starting to go. You changed everything except this. Is the sound ticking or clicking? Does it sound mechanical or electronic? Where is it coming from? What area or part? More info will warrant a better answer!

sounds like your fuel filter might be plugged causing the engine shutdown. sounds like the solenoid on the starter is sticking causing your starter to stay engaged and powered up. the starter will stay powered up and will continue to spin until the starter solenoid is disengaged. one other area to look at is the ignition switch. if that is bad it will continue to send a power signal to the starter solenoid keeping it engaged. so, you may want try unplugging that first, while your starter is running. if continues to run, then i would say it is the starter solenoid and not the switch. good luck
I own and have done many modifications to my own 86 Bronco II (B2), but the fact of the matter is, 2.9s are just not powerful engines and their brick shape just isn't conducive to great aerodynamics. From the sounds of it, you have done almost everything you can to increase power, and what I can tell you concerning additional modifications to the stock engine really won't make a difference as far as horse power is concerned.
Some of the options available to you will be either a 4.0, 5.0 or 5.8 swap. However, they are all time consuming. The B2 ended in 89 and was replaced by the Explorer in 90 with the 4.0 engine. The 2.9 transmission bolts up to a 4.0, but you will have to deal with splicing the 2 wiring harnesses together and running the Explorer computer.
If you want to go V8, the 302 swap is the "easiest" of the 2 due to clearance issues. However, you will have to swap out the drivetrain, axles, cooling and various other parts of your truck. WWW.JAMESDUFF.COM and other places have books that you can buy that are specific to putting a v8 in a B2.
Unfortunately, there are no kits for swapping engines in the B2. It is most certainly a do-it-yourself project for people with the motivation to get more power out of a B2

The 89 bronco's are running a OBD 1 system and the check enginelight can be reset by disconnecting the battery for about 5 min. But if there is an issue with the engine management system that needs to be addressed, the light will come back on again. If there is an Auto Zone around your area, they can check the bronco for the DTC codes for you to address the issue and they check free of charge. Good luck and keep me posted, be glad to help you get your bronco running 100% again.
