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!

Will the injector problem also apply to the V-6? Mine was only having a surging issue at idle and it normally does it when it is cold (under 30degrees f) however it’s happening on acceleration and even after the engine warms up.
Thanks for any insight.

Which year? The 88/89 3.0 uses a TBI injection system that can act up if the injectors start to age. The easiest repair is to just replace the injectors. They also can have issues around the idle air control unit. That can be tested using a quick spray of carb cleaner at the IAC seal areas, if the engine rpm changes the seals are stiff and failing.
