Topic: Not that I am looking for another project -- 19lb Ford injectors

[chrisfranklin]

My Yj passed the CARB tests last go around with the bored out 4.0TB on there.  Only thing is that I still feel like the engine is running lean. 

I know the engine state of tune pretty well and everything is clean, filters are in order, fresh oil etc, engine flushed, fuel system/filter clean.  Still seems like the engine is starved for fuel at part throttle (or maybe the timing is somehow "retarded" for some reason)

You guys think these Ford injectors might help out with this (if leanness does, in fact, occur), think its a sure fire way to bomb a CARB Test (probably not), or you think its a mod really only helping at high RPM?

You need an actual air/fuel gauge otherwise you're just guessing.

Good point. I'll have to look one of those up.

Don't trust those $40 Autometer A/F gauges. They do not work. You need to use an actual wideband O2 sensor.
