[QUOTE="1wild-horse, post: 16937927, member: 84197"] I even have the failure logged that shows exactly when the line blew off. The data before it happened was perfect. Good A/F 75-80, pump duty cycle from hi 70's to low 80's, rail pressure at around 40..once I hit 3rd, the duty cycle dropped along with the input voltage, pressure went to 50..I'm guessing that's when the line blew off, then it commanded less pump..but putting the line back on should have fixed it. That's what's baffling me. What the hell else could have happened at the exact same time that would cause fueling to not return to normal once the vac leak was fixed? [/QUOTE]
