Hi,

I drive a GU II 4.5 L dual fuel Patrol and recently towing my 2.3T van up long steep hills e.g. Mt. Ousley south of Sydney, it was like I had the brake on - down to 1500 revs and 10 kph in first!!

Nissan found that it was a blocked catalytic converter in the emission control system - and once replaced, Mt. Ousley going home was no problem at all.

The Patrol has done 110 K Km, approx. 30 K Km on dual fuel, using ULP after every 3rd or 4th tank of gas.

Can anyone tell me, please, what causes the blockage and how to avoid it in future. The replacement converter cost me $500 plus $170 for trouble shooting!!

Thanks for your help.

Pete
