my thermostat in the au was the cause of ridiculous fuel economy.
300k to a tank out of a bog stock au autom mainly highway k's.
18 bucks for a new one and that fixed it.

Replace the rocker cover, i have a nice one of a EF XR you can have for nothing, I am in Berwick and it is yours if you come and get it. Oh sorry i have to say this..... Spider Pig, Spider Pig, Does what ever a Spider Pig does. OH, and try putting a brick under the accelerator, that will fix your fuel problem.
