93 z28 383 stroker have minor problems
this car has been upgraded with a 383 stroker with headers and performance exhaust msd spark amp coil and distributor and full rear suspention the current problem at the top of the list is fuel related.. when driving uder normal street driving the slight feather of the accelerator couses hesitation and sputtering although when opened up it runs great all the ponnies you want its also running very rich which im sure its related. at this poin i want to make sure the money goes to the right places ive been told the hyper chip and stand alone management is my only option i hope that is not accurate

scann for trouble codes and see if anything comes up. test you evap system, check for vacuum leaks, check air filter. could be stuck injector or failing 02 sesors. take the 02's out and see if there fouled. does it have a chip in it? what tb are you using stock?
