Vacuum leak
Hello. Recently I tested and diagnosed two knock sensors and replaced them, however in the process of reassembly I made sure all of the vacuum lines are connected. Despite retracing my steps and double checking where I installed the hoses, I still hear the obvious hissing of a vacuum leak near the upper rear of the engine, where I removed the intake. I'm wondering if I overlooked a installation step, I broke a hose, or 90's GM plastics finally broke. Plz let me know if y'all had this issue when removing the intake manifold.
Thank you
Thank you
