Using.

Some verbs cannot be followed by a verb in the infinitive. Favor is one of these verbs.

There are lists of some of the others here:

Using Gerunds and Infinitives

Verbs Followed by Gerund and/or Infinitive

But neither of them has a full list. I noticed that favor (or in British English, "favour") doesn't appear on these lists.

As Boothling has indicated, this is an area that requires memorization and practice.
