    Here is your post:

    Check the spark plugs, to ensure that it is not a distribution problem.

    On fuelling check that fuel has enough pressure, and that air filter is ok and air intake is not obstructed.

    If the problem is nor fixable with regular maintainance like the operations above, then you will need to connect a code reader to the car ECU (computer) , and start troubleshooting from the error ccodes that you get.

    For your car you need an ODB II code reader.

    Here is a selection of code readers working on your car. The ones below $100 are often useless. A good one with full features costs over $200.

    From description I do not think it is fuel either, but sometimes a bad fuel filter or an bstruction on fuel lines can do funny things.

    The small code readers have a limited set of functions.
    If it was a carburetor car you had to adjust just the air and mixture screws to get it going.
    On Electronic fueling you need a professional code reader to check the air mixture, and to test malfunctions like the MAF sensor that can cause similar problems.
    See here the difference between a professional scan tools and a basic code reader.
    Here are error codes for Ford ODB 2 cars.

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.
