Hard questions, for sure engine and EFI swaps
no photo of engine presented , our gallery does work.
I'D say bad spark wire sets. (but are new)
get NGK mag wire. wire sets. they will not fail. (mag wire ups the spark power and all these cars need that)
or bad MAF (or just dirty)
is the MAF connected to stock air cleaner, I bet not and the one there is no good. damp, so called cold air intake , loves to fail, as the Air filter is exposed to rain
as it splashes up to non stock air cleaner fitment.
MAF dead or just dirty, clean it first. the hot wire must be cleaned,
the spark plugs are not queer right, just J- plugs not 2J or 3J or some crazy bad surface fire spark plugs and gapped to spec, under hood sticker lost tells this.
gap is 0.028" not wider. ever.
the maf on the new car 1994 , had a nice air cleaner box.
this box keeps the filter dry, and also keeps gross humid air from landing on the hot wire.MAF elements
humid air there will make it read too high and over inject.
the MAF things air is 2 times normal like that. Stock works best. (air flows ,)
most swaps like this use those silly cone filters. sitting in space and some seen are bouncing like mad that will wreck any MAF fast.
all maf tests by me shown here Exel plotted, I even used lawn leaf blower to test a maf, to full output, (look ma' no car!)

if the ECT pins are rusty it will read wrong mostly in rain. (humidity)
here is one poster that nails this best, cold air bull it is called.
sucking hot air of the back side of the radiator and full of rain water too.
