What would fix this? It happens every now and again. Twice both 1 and 2 read lean. Is there anything I can do to fix this. Other then clearing the codes when they pop.

1996 350 5.7L 80MM throttle body, aftermarket mass Air flow, K&N full intake, MSD Coil, and short Headers.

I replaced the O2's about 30,000 miles ago maybe less.

96 Chevy 1500 5.7l
