CALLING ALL MECHANICS & CAR SAVVY PROFESSIONALS!?

this is specific but happened to me , ford taurus as well the throttle body has a filter in it it is not in any manual , they become clogged I changed a lot of stuff btu the dealer found it and there was no charge , the filter only stops working at high engine speeds and not for long ,,, worse when hot ....good luck (single throttle body ) think it was 2.4 or 2.2
