ok today while running errands i got the engine fail safe program what the f---k now.i got it towed home started taking it apart cause the code was throttle body fail to respond something like that. well i started to disassemble it, and when i got to the throttle body i saw this look at pix where the hell is that from any way i took it out reassemble it back together now it idles high=1200rpm instead of surging but still in fail safe mode could this part have gone bad by the rubber jamming it shut.?? i only get from 650 rpm to 1000 rpm respond when i step on the gas in drive no power.this truck has been a omen since i bought it in may-2014.
