The 1987 2.9L V-6 has SIX injectors.
if its a full size fuel injected bronco 87 or later the pressure should be between 35 and 42 psi
depends...does it have a carburetor or fuel injected..?
I just get a bottle of fuel injector cleaner additive and pour that into the gas tank and let it do the job.
If you're sure it's a fuel problem, check the injectors and fuel pressure regulator.
Replace fuel pressure regulator.
maybe the fuel pump is not supplying the fuel as it should check the fuel filter and the pump pressure or the air filter is clogged
mine are blue, but there all different. 89 are black, 87 are blue, 92 are steel

Its a manual / mechanical fuel pump. To check it remove it a look inside. It will be obviouse if its bad. More importantly if its running its not bad. There are no injectors on a 87 Grand Wagoneer. Its corroborated.
i had an 87 Chevy s10 and it was doing that same exact thing at and idle it would push too much fuel and i changed the map sensor throttle positioning sensor and the whole works and then i decided to just change out the injectors and the fuel regulator. That fixed my problem hope i was some help
A higher octane fuel(94+). Shell has a lot of cleaning additives to their fuel, up to four times the industrial standard. All gasoline today has additives added that help keep injectors clean. There is no more cleaning additive in Shell 94 octane fuel than there is in Shell 87 octane fuel. Using a high octane fuel in a vehicle designed to run on 87 octane is a total waste of money and provides no benefit whatsoever. Once each year add a can of Seafoam, Techron, or any other high quality fuel system cleaner to a full tank of fuel and you will be fine.
I own an 87 Cobra GT with a 306, E303 cam, GT40 heads and intake, 24lbs injectors, much, much more and a Vortech Supercharger.....at idle, fuel pressure is at 42 lbs.
