Lowering Idle Fuel Consumption
In my 2003 Jeep Grand Cherokee with the 4.0L, according to DashCommand, I’m using 1.2gph at idle with the A/C on (it’s about 0.9-1 with A/C and all accessories turned off). This just seems too high, meaning I would be able to idle for only 16 hours on a full tank. Does anyone have ideas to lower idle fuel consumption or find the culprits? (I run E85, but gph seems to be about the same on 87 octane).
