Question about 2001 Ford F150 Styleside SuperCrew
PO 171 & 174-are O2 Sensors Codes,forget them,just be sure their screwed in tight. Yes ,they will come loose.
PO303-is a bad COP Coil,on #3 cyl ,may be one issue,very common on all ford products
PO-403 -is EGR related.-That probably is shot, also.
Had all thoses and more, on my Lincoln Ls
A misfire will set many codes,that while not unrelated,are not your issuse. You need to understand the symptom,is not always what caused the codes,or not the cause of the problem.

Malfunction indicator lamp keeps glowing even after engine starts but no problem while running or at the time of starting the engine-is it harmful in the long run?
