I told them I never cleared the codes since I last read them and to re-read the codes with my Mac Tools tool which I keep in the car. They did get those again, but said they are generic codes. They did a smoke test after that and found that thete is a leak where the vacuum tube goes from the brake booster to the intake. It doesn't appear that this is a serviceable part, so they recommend replacing the intake. Stealership price for an intake is $2300.... lol. They already knew my answer to that. I'm picking it up tomorrow and it'll get a bead of black RTV. Hopefully this will be problem solved. I'll report my findings.
The vacuum line from the intake to the brake buster
is serviceable. That fitting on the intake is a quick connect and you can remove the vacuum line by first unscrewing the black outer ring then you will see a colored ring that is pushed forward against the intake and the vacuum tube is then wiggled loose. It is not the easiest thing to do, but that vacuum line will come out. BEFORE YOU SLATHER SILICONE AROUND THAT FITTING YOU SHOULD PULL THE VACUUM LINE OUT, INSPECT THE END PIECE AND THEN REINSERT. I hate to see you gunk something up for the next guy, if it can be avoided. The vacuum line at the brake booster is just pressed into a rubber grommet. It too is not easy to remove, but with some wiggling and a little WD40 will come out.
