appreciate the humor
I bought the car used and don't drive the car hard. If anything I am very conservative. This is my third mustang in the driveway. I have replaced all the things you might think of: fuel filter, plugs, wires, O2 sensors. I have had two shops run scan tools on the car but no luck. I ran multiple cans of Seafoam through the system (both tank and brake booster line). I even took off the upper plenum and cleaned the ports. Now the car is killing when coming to a stop (not all the time). It feels like the car is sluggish due to fuel being dumped into the system. The techs seem to think it might be the vapor canister or a vacuum leak. Eventhough I have tested the vaccum at idle they think I could have a small crack in a hose that only causes the problem at high speeds.
Does anyone know how to get a copy of a vacuum diagram for 2001 mustang 3.8L?
