Re: 2001 F-150 5.4L Will not start when outside temperture is cold
I had that problem it was the air intake sensor. Remover it and spray the tip with contact cleaner and gently wipe the black stuff off with a q-tip, be careful its easy to break. if thats not the case high performance spark plugs help greatly. evan if they say they dont need gapped always check. the gap for your truck is .052-.056. before you tear into it, how many cold cranking amps does your battery have and whats your oil weight?
