P1128 and P1130 - only after a few sessions of "spirited" driving

[sb01box]

i've had the same 1128-1130 code pop up on my drive home from work.
spirited freeway driving for about 7 miles
on to city street at about 40 mph for 1/2 miles
while coasting to a stop at a red light, the CEL lights up
always 1128-1130 combo.
clean maf and did the job for about 1 year.
started to get the same code after same drive.
replaced maf. no more CEL 1128 1130 for 2 years now
