Hi I have been trying to tune this 2008 ford 4.6 5 speed that was transplanted into a 65 ford fairlane. Runs great but will throw a p2104 tb code. go into reduced power. i followed Eric Brooks tuning guide (thank you) but i can't get it to stop going into reduced power.
car has a cold air intake, BBK throttle body, shorty headers no cats.
can someone look over this please and see what i missed?
i have not ruled out a faulty throttle body.
10-21.hpt
Thanks
Malcolm
