Loss of FP obviously, jerky idle. The first symptom was the smell of HTS coating cooking off. The fuel pressure was dropping at idle and leaning the car out. The hotter EGTs then cooked off the coating from the headers. When you have new exhaust smell and your exhaust is two years old, you know something has changed.
