Two months ago I changed all four O2 sensors and MAF sensor. Replaced a split manifold vacuum hose. Motor runs great but heated O2, O2, Cat and EVAP monitors will not complete. Have done cold start drive cycles each day but monitors wont go to ready.

What is your question?

Five months ago I realized that I was getting very few miles to a tank of gas. Motor began to idle roughly, but was ok stoplight to stoplight. But eventually motor began to stall at each stoplight. O2 sensors were replaced with Ford O2 sensors. But the motor began to run more roughly. I found a split manifold vacuum hose and replaced it. Then found that the MAF sensor had gone bad (tried to clean MAF sensor with no improvement). (Motor ran better with MAF unplugged). Replaced the MAF sensor. The motor idles and accelerates well. MPG is great. I just need to complete two of the four monitors. If you know how, please help.
