I’m out here testing everything I can think of that’s vacuum related, not done yet ( maybe for the night ) but here’s where I’m at so far. Vacuum ball holds a vac, cruise control holds a vac, there is a line that splits off a tee that shares the same line going to the cruise and vac ball that goes into the interior on the pass side by the ac box ( I’m guessing for the ac controls ) that is not holding a vac so I capped it for now but still no change in vac reading. I disconnect the vac line going to the PCV valve ( RJC valve with not manny miles on it ) and cap that vacuum line and vac gauge goes to around 14 idle 12 in gear. What does this point to a bad PCV or possibly something else ? If PCV which ones are you guys having good luck with ?
Thanks
