I'm told most came to Australia less CATS & o2. True? Some imported from Japan have them. My issue is a very thirsty 94 RRC low on power so the process of elimination has started...Assuming no CATS & O2 is normal, where should I start? MAF, Coolant Temp sensor, CAM? Need more power and less fuel...stop laughing!

there is a potentiometer on the MAF to adjust the mixture for non O2 setups.

What do you consider thirsty? My ‘94 LWB is running very well and gets 12mpg unloaded, loaded, around town, highway driving makes no difference. 12 it is. Cats and O2 sensors in place.

Had a 3.9 in my 1967 Series IIa 109 SW. No cats yet there were 2 O2 sensors before the muffler. Always thought the 14CUX needed them.
