I have a B16a in my 90 CRX Si. For awhile now Ive been having this misfiring problem but recently it has gotten worse and almost caused an accident. Sometimes when I give it light throttle it just doesnt respond at all, just like Im coasting. It I give it more sometimes and spring back to life but sometimes it will not respond at all again. This happens mostly while Im coasting in gear then get back on the gas.
These are the parts that are new/valuable info:
Fuel filter
Spark plugs (gapped correctly)
Pr3 Chipped with BRE stock pr3 bin 1 o2 sensor
Throttle cable is fine.
New obd 0 Dist.

Questionable items:
APC plug wires, unknown age but seem to be new.
o2 snesor age
Injectors
FPR (B&M but unknown age)
TPS (havent tested it yet, not sure how)

What do you think this could be? I dont want to go spending money for usless stuff if someone may know the answer.
