Ok, not the ignition switch as the car dies like getting "choked" and happens at the same mileage/temperature consistantly. In addition to all the sensors, plugs, coil etc, that I mentioned in previous posts, I had just done the ECT and the Map/IAT sensor. No change. Had an idea on the temperature thing. Can the cat get hot enough or pluged up enough when hot to kill the engine? I read that the ballasts inside can shift over time causing it to block when hot enough. It then effects the Vaccum system as well. Considering the car has been hit at least 5 times over the years, iy is certainly possible that the insides could be toast. There also is a vbibration rattle noise inside the cat when running. Anybody think tjhis could be it??? Last shot.
