96 LT4, Rebuildt at 140k car now at 155k.
 
Got a strange one...Motor starts ok, then when I strart diriving breaks up and then smooths out(kinda hesitation).  When I hit full heat, runs OK or toloable.  It is throwing a code... will pull code today.  Since it started hoping for an easy fix I did the throttle positiong sensor(not it!).  I am thinking bad fuel or clogged injectors.  Plan on changing the fuel filtier today and investign in ACCELL injector...   Any other thoughts?

Ran code - O2 sensor $60, also changed the injectors(very simple) - Big improvement!  Pass it on...
