Owner report 759063 · 2002-03-07 (March 7, 2002)

I AM AN EXPERT ON THE 2ND GENERATION 1986-1991 RX-7 VEHICLES (SEE HTTP://FC3S-PRO.COM). I FIND THESE PULSATION DAMPER FIRES TOO COMMON WITH SERIOUS/EXPENSIVE DAMAGE - TYPICALLY WILL BURN WIRING HARNESS ($1,200) AND ALL FUEL INJECTORS (4X$300) UNDER THE MANIFOLD. MAZDA AND ALL MAZDA DEALERS REFUSE TO ACKNOWLEDGE THIS PROBLEM. I WISH THERE WAS A MANDATORY RECALL ON THIS PART, AS THE POTENTIAL OF ENGINE FIRES IS WAY TOO DANGEROUS. PLEASE FEEL FREE TO CONTACT ME. I AM ALSO VERY CLOSE WITH THE INTERNET COMMUNITY OF THESE OWNERS. *AK
