Actually I drove for a week after I replaced canister set. But I am
driving to work around 12 miles on each way on highway, may be that is
not enough to adjust drive cycles I think. I am driving at 60mph for 2
minuts, 70mph for 2 minuts. As per you suggested I will drive for an
hour over the week-end. The guys at DMV said, "bring the car after
drining for an hour on highway", this wasy engine will be hot and they
take the reading again.
