The automatic certainly isn't helping anything as you probably use more throttle to get the car moving than you would with a stick shift.

After 4000 rpm it goes to a single fuel setting and, IIRC, ignores the O2. To get maximum milage with the stock ECU you have to drive less than 4000 rpm. Option 2 is to get an aftermarket ECU. Option 3 is to put a 3.909 rear gear or .75:1 5th gear to lower rpm. Randy Well I was researching the OTM Dodge Neon I will probably be buying, they have 2 liters, are 300lb heavier, with 20% more horsepower and get 50% BETTER gas mileage (high 30's highway) I wonder if the 1.6 Miata runs rich by design or something. I mean it's a lighter car with smaller displacement. Could the O2 Sensor be intercepted top force a leaner condition for cruising? _____ Wondering what's for Dinner Tonight?
