Hi All,
I've noticed my '99 3spd has been using more fuel (12mpg) lately (16mpg is normal) but I put it down to only doing very short runs. Took it out yesterday for a 300km round trip to the farm and noticed a couple of things:
1) Mileage was still poor - 14mpg
2) The aircon would switch to defrost under load, going up hills etc
3) Seems to be slightly down on power but hard to quantify
I know the Aircon issue is usually indicative of a vacuum leak and am going to go through the system shortly but could that also be causing the fuel usage increase? No noticeable other symptoms - no unburnt fuel smell or stalling or uneven idle.
