So I fixed my lifter noise problem, so the last problem needs to be addressed. When I start the car to let it idle, my vacuum is like 5psi, I know that sr’s should have 16-20. I took the car for a drive and when driving the vacuum sits around 20 and runs good, till I come to a light or stop sign lol. I sprayed looooots of quick start all over the place and am yet to find anything. Just wondering if there is any other places or things I should be looking at before I pull off the intake mani to swap IACV and change gaskets and such, thanks in advance.
Check the inlet hose to the MAF, there might be a leak in it.
