My 3.0 is running rich- at least that is what the error codes are saying. I noticed a big drop in gas mileage- 240 miles per tank to 140 miles per tank. I keep getting the CEL when I am idling. I keep pulling the EFI fuse and that clears it, but it will come back when I am idling like at a stoplight or something, but not when I first start it up in the morning. I heard somewhere that the injectors like to start dribbling fuel when they are old and worn out. I imagine that could cause a rich condition. Anyone know how much it will cost to get the injectors rebuilt or replaced? I have replaced both O2 sensors at $120 each already and no improvement! I am out at sea in Southeast Asia right now, so I can't get it fixed until we get back home again. Thanks in advance! :help:
