id be willing to be its injectors, exact same symptoms i had, it cost me about 650 for the lt1 injectors and installation combined. its alot of labor and had i know it was as simple as it is i would have done it myself...but it is my daily driver unfortunetly. a good set of lt1 injectors or aftermarket will do the trick, runs a little rich without tuning but much stronger and more efficient than the old ones. i was told lt1 injectors are less likely to clog as well.

 

can LT1 edit be used to identify these problems? I have had the same problem for about a year or so but i have heads/ cam etc.. Im sick of guessing at what might be wrong with this. What program etc do i need to get for my laptop to diagnose whats wrong with it?
