THE CAR IS A DAILY DRIVER AND HAS NEVER BEEN DRIVEN BEYOND THE AVG DAILY ABUSE. ONE DAY I RETURN HOME AND IN THE DRIVEWAY THE CAR STALS AND I START IT AGAIN AND IT STALED AGAIN, UPON OPENING THE HOOD I"M GREETED WITH A BBQ SIZE FIRE ON THE INTAKE MANIFOLD. I PUT IT OUT WITH WATER AND LET IT COOL, BEING A MECHANIC I REPLACED THE PULSATION DAMPNER WITH A BANJO BOLT TO FIX THE PROBLEM.*AK
