These vehicles are semi notorious for intermittent mechanicaly sticking injectors. This will cause surge, missfire, stalling ect. This is somewhat maddening. It is worse when the engine is fully warm on a hot day. There is no easy way to diagnose this. Prosses of elimination. I personally have the same problem I have 25 yrs. Master auto tech with L1. I have a 88 Z24 pickup myself. I'm in the prosses of looking for rebuilt injectors. New ones cost 240-290$ each!
