When my 92 Ranger 2.3 had nearly 170,000 mile's I dicided to rebuild it. (It was getting tired) I did all the usual thing's like .030 over bore, machined the crank, reconditioned the rod's, new cam & follower's, you know the routine.But I went a little further by using Forged piston's, "Moly" ring's, and slightly larger cam. Had the block, head decked a total of .040. When I started driving it I got a " Check Engine" light. The code said it was running lean. After adding larger injector's ( 4lb's) got another light saying it was rich. After talking to a few racing friend's I installed an adjustable pressure regulator and upped the pressure by 4 lb's, and now the truck run's great with more power and fantastic milage.( nearly 33mpg on open road)
