Once upon time there was a popular swap mod replacing the stock 4.0L single hole injectors with Dodge Neon 2.0L four hole injectors.
Supposedly the better fuel atomization made for a smoother idle and slightly improved gas milage.
IDK if the information still out there but you might want to look at what's involved.
