Hey all

I have a 2003 F-150 Lariat 5.4L
I have installed an Airaid Air intake and an Magnaflow Exhaust.. that was about a year ago.. over the past 4 months my oxygen sensors have gone out twice... is there a way to cure this problem ie different oxygen sensors, programing the computer?

thanks for your help

 

Um, what makes you think or how do you know that the O2s are bad?

 

Well 2003 u may want to think about some mil elimators.

 

They went out in december.... or so the dealership said.... lol.... and engine light just came back on and my truck is acting the same way as before.... no noticable problems while idleing or driving so pings or knocks coming from the motor... ive got a scangauge on the way.... i was wondering if anyone has had or heard of problems with the oxygen sensors going bad on a regular basis

 

What is the code you are getting when the CEL comes on? I doubt your O2 sensors are going bad...probably something else.

 

Indeed.

Pretty unlikely. Probably a mis-diagnosis.
