Bronco Ii Help!!
I have a 1989 Bronco II with a 1997 Aerostar 4.0 in it.
It was driving fine then all of a sudden it just had no power. I step on the gas and it revs very slow and will not rev past 3000 rpm and does a lot of chugging.
I checked fuel pressure, replaced 02 and checked through replacement most other sensore. I replaced coil pack and wire and plugs. I am getting spark. While running I can remove all the plug wires from the drivers side and there is no change in the running of the vehicle which leads me to believe that the fuel injectors on the drivers side are not providinng fuel. Can someone HELP. Is this a computer problem or is there a Injector Controller somewhere?? Again it is a 4.0 Litre 1997 Aerostar Engine.

Just a stupid question, Did you put in the Aerostar ECU? Did you make the appropriate splices where needed.
I have not done the 4.0 swap( still in the process) But I know of a lot of people are experiencing problems due to the wrong splices.
You may want to recheck everything to make sure you have everything spliced correctly.
