I'm pulling a code 33 and 77 on my '92 Ford F150, 5.0, 5spd manual. I think the 33 is the EGR valve, but what is 77? If the 33 is the EGR, does that mean I need to change it out, or could it be some of the other fuel mixture/exhaust components, like the O2 sensors or PCV? Thanks in advance for the help. -Al Nobles

33=throttle positioner sensor noisy/harsh on line

77=brief wide open throttle not sensed during test

thanks for the info

Before I replace that, is that also the possible cause of my throttle sticking when decelerating or pushing in the clutch? Thanks.
