Here is the sentence:

Jim would have driven faster if his mother had took her own car to the mall. Instead, she rode with him, criticizing his every decision and shrieking hysterically whenever he ran a yellow light.

The second verb, had took, is the problem. As you know, this verb requires the past participle because of the auxiliary verb had. Had taken is the correct form.
