Other people seem to have had this issue but I haven't found anywhere where it was resolved.The issue I'm having is my car will die whenever I touch the brakes including at idle. I drove the car with no issues about a month ago and came back to the car last week and since then I haven't even gotten out of the driveway. The car idles fine but as soon as any amount of brakes are applied the RPMs drop and the car dies.I had a second 98 GT which I just sold that I used to narrow down the issue such as swapping the entire upper intake manifold which includes the TPS, IAC, and MAF but the issue remains. I also just put in a new VSS. I know the brakes aren't vacuum assist otherwise I'd disconnect them to diagnose this.The car is fairly new to me but as far as I know it has a PI head motor out of a crown vic as well as a 5 speed transmission out of a 99-04 due to the shape of the VSS. Otherwise no crazy mods just a 76mm TB, upper intake manifold, and a K&N intake.Any help is appreciated!</blockquote>
