I took my 1999 Ford Ranger (4 CYL.) into FORD the other day for it did not run right, the timing belt was bad and they changed the Plugs and wires on it.

It still is not running right, so they are changed the Air Sensor. They believe that my K & N Air Filter left a piece of dirt into the Air Sensor and caused it to go bad.

They believe that the New Air Sensor will make it run like a New Engine once again.

Has anyone had this problem?

Could it be because it was in a accident before I brought it, that is all I know about it. But I found out that it had a Stainless Steel Exhaust system on it when it was NEW. But when I got it no longer had it on. So could the dirt got into the Air Sensor than and when I brought it 4 years ago? I never noticed it run bad until this Winter. Yes it has 85,000 miles on it.

My question is : The K & N Air Filter a bad filter?

Ford thinks they are, and feels that the K & N Filter was the cause of the Air Sensor to go bad. They feel that the paper filter is the best, and that it would not have let the dirt go through it, and caused the Air Sensor to go bad.
