This truck started Idleing bad, plus the power brakes don't work. I check the pcv value replace the vacuum value on thr brake boster, check for vacuum leak(cant find any). I pull off the vacuum line from the boster and the motor runs better but stills misses there is lots of vacuum going to the boster when i put my finger over the line the motor wont ot stall.whit everthing hook-up the motor aks like it's not getting enough intake-air.????
