87 4.0 aw4 with a 88 motor and trans running great 31 bfg mts and 3.55s. Exaust, advanced timing and a CAI pulling air from the cowl chamber. Just got all my sensors in check after a bad o2 I suppose foulded from the bad coolant temp which must have been making it run rich as hell. Still getting about 10 mpg city with a little wheeling every once in a while and a couple wot races with the local ricers. So I suppose I could maybe do a little better and thats better than whatever I was getting before but I drive real conservative for the most part. I feel I can get 15 and am trying to figure out where I'm loosin it. Not much left to replace except injectors especially if they are the 215000 mile originals. Can worn injectors be a source of running rich? I'd like the upgrade them anyway. Then I'll get to the adjustable map eventually. What are your opinions on gas mileage? I know its one of the hardest performance aspects to deal with and improve
