Good advice Wes. I was doing just that on my old TJ . And again on the JK. But senility has set in i guess and i don't know where I put my log book

Well it happened again today afterwork. I started up my baby and left without sitting idling. The km/l jumped up to around 165. I drove along a side street for about 10 min before jumping on to the highway. It took just under 30 min before it came back down to normal (about 13L\100 km ) My gas gauge read 1/2 full. Any input is appreciated.

Don't reset the meter, ever. Initially after the reset, it will be way off until you get some k's on it. The more km's since the reset, the closer it will be to your actual average.

Actually zrs, i didn't reset the guage, I just kept driving and the L/km started decreasing on their own till eventually settling in at 13L/100km.after a half hour. I'm going to have to take her in when I find the time while shes still under warranty.If I reset, I guess my average fuel consumption would be comparable to modern airbus.

There's an analogy! Lol. I'm thinking there must be an issue then. Are you noticing any other issues, ie shift points off? You have to look at the operations through a scan tool, to make sure the computer is receiving correct data from the various sensors related to that circuit. Pretty tough to diagnose without seeing that...time for a trip to the shop. (Hanger)
