Pull the vacuum hose from the map sensor and if your idle smooths out change the map sensor. About a $20 fix.

Interesting problem... I myself own an 88 Ford Bronco II 4wd 2.9L V6. I have issues with my idle reving up to 1500 to 2000 rpms at stop. I have not yet resolved the issue, however, I do believe that sometimes electronic components are to blame...such as the brain or "Mother Board" of the vehicle. I replaced the "Brain" on two previously owned vehicles with instant results. I would suggest the local junkyard for a try...only as a last result. The "Brain" is located on the passenger side along the Interior wheel well. If you look along the front passenger side wheel well inside, beneath the plastic, vinyl, etc....you will find a metal enclosure that is comparable to a computers cd drive or hard drive........Approx. 4" x 6" give or take. The Board will have a wide slot plastic attachment plugged into it...very similar to an IDE slot on a computer.
This is the Brain......for your Bronco II.
Buying a used Brrain is a Gamble ...
You could get a bad brain!!!

BUT...You could get an instant repair!!
Who's to decide?
I had an 1986 BMW 325I
Suddenly One Day....
It started Reving up and down erratically....I was at a loss.

Luckily, I had a friend who was a BMW mechanic, and informed me that there was a relay in my glovebox that controlled my idle. I took a chance and tried replacing the relay with one I purchased at the junkyard...although they wanted $50 for it...I was willing.....and the new /USED idle conrol relay turned out to be an affordable fix. Thankfully

I have an 1988 ford bronco 2 automatic V6 i pulled


There are shift solenoids in the transmission and apparently there's a problem them. I would get it to a trany shop and have it checked right away. If you continue to drive it you will ruin the transmission. Are sure you put the right computer in the vehicle? If you put a computer from a Bronco II with a manual trans in a vehicle with an automatic trans, the trans won't work right.

Rough idle up and down 1988 ford bronco has a new Idle Air Control Valve was thinking it could be the MAP sensor or the coolant temp sensor anyway tho check either of these.


Try discoonecting the battery for a few minutes, and then reconnect and drive it, it may have to "relearn" proper idle speed.

Why does my 1989 bronco II lose power after it gets warmed up? After taking off from a stop, I have to floor it to get it moving, & it is slow getting up to speed.


does it feel like it is running rough? a mis fire could cause this and if it does it when it warms up you could have a fuel riching mixture problem.

how does it feel>?

1988 Bronco 2 stalling out.


have te ignition module and stator been replaced? that is the common cause of this, and yes the engine being out of time can cause this stall out, when you time the engine remember you must remove the timing shorting bar at the distributor connector to the TFI ignition module or the timing will be severely retarded
