It could be almost anything. There are several system that need to cooperate for the engine to run properly, any one of them slacking off, will give you issues. Don't just throw parts at it, plug a scanner into it, and see what the PCM thinks is going on.
Need to look at data while the engine is running. Fuel trims, coolant temp, etc. See what gets strange when you step on the gas. (or, simply starts out strange....)
Well basically have replaced about everything besides map sensor o2 sensor coolant sensor and the idle control motor lol so I’ve replaced a crap load of things that would cause it to do that so far just puzzles me like crazy ha I put all new suspension in new rear end new u joints and everything listed above trying give old truck new life just won’t let me love it..
