July 16, 2011Help; My 2006 F150 5.4 XLT is running bad. Only when it warms up it starts bucking, coughing, etc. If I pump the padel it gets moving after acting up. I have changed the upsteam OX2 senors (lt/rt side), cleaned the MAS and to replace the TPS. My truck has never ran this bad. Any help is much need!!! Thanks

Rom 5:8 But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.

July 17, 2011When it starts acting up,try to get it to keep doing it as long as you can.
Sometimes it takes a wile or a hard miss to through a code.
