ITS THE BASICS!

FOUND OUT THAT THE CATALYTIC CONVERTER HAD A LOOSE CLUMP OF CATALYST @ THE INLET CHAMBER WHICH OVER TIME BEAT THE REAR CATALYTS' HONEYCOMBS ALL TO HELL AND RESULTED IN A MASSIVE FLOW RESTRICTION DURING ACCELLERATION!

(FUEL FLOW OK, 1 + LITER IN 30 SECONDS)

MANY THANKS TO WAYNE'S VW REPAIR IN WEST VALLEY CITY UTAH FOR HIS
TIMELY AND USEFUL ADVICE, GREAT GUY , GREAT HELP !
