My truck is doing some weird things at low speeds and a cannot figure out what is causing it. when I accelerate very lightly my L/100Km jumps up to the max, but levels out to normal once I am up to speeds. When I am braking everything is good till I hit about 30km/h then I jumps way up again. driving at highway speeds everything is normal. makes no sense to me. I recently put a 3inch front and 2 inch rear leveling kit into my truck, took it in for an alignment, my battery died while it was there and it had to be boosted. after I got it back I started to notice this weird behavior. I'm lost, anyone else have something like this happen?
