I've driven my 2000 MT since July and only recently began to recognize lean burn. Mostly l have been driving too fast plus we have lots of hills. I just bought an Ultra Gauge UltraGauge Automotive Information Center and OBDII Scan Tool due to a recommendation from uhtrinity and now I can really confirm and identify LB characteristics. I just did 600 miles this weekend around the Olympic Peninsula in WA state and averaged 71.2 which is at least 12 better than I would have achieved a month ago. Mostly I am driving slower, as I have been unable to get LB above 63 mph or so. I think I'd be averaging at least 75 if I drove 55. The Ultragauge is programmable with 32? gauges available. I use % engine load, engine Temp, both o2 sensors, intake temp & TPS. That fills the first page. I have not added any gauges on the next 2 pages that are available. Very educational. Highly recommended.
