need help intermittent rich and car will shut off

So car ran fine with 39lb cobra injectors but was leaning out up top and caused a head gasket failure on my car. I bought a set of 60lb injectors and a maf calibrated for 60s off of the classifieds here. the car has been tuned and runs fine with great a/f ratio and such. intermittently the car will go pig rich and cough sputter and eventually stall out. could it be the injectors or am i missing something

multiple things can cause this issue...

just a few common possibilities...

bad/stuck open injector
bad o2 sensor commanding more fuel
Bad/dirty MAF reading incorrectly and commanding more fuel
