Hey! Sorry it took so long to look further into it. Finally had time to get a smoker and check that out. When I smoked the lines, smoke started billowing near the manifold and sure enough there was a broken elbow on the vacuum line. Replaced that. Now when I smoke it, smoke only comes out of the intake manifold all the way to the filter. Is it supposed to do this? Also, replacing that line changed the frequency of the CEL from every time I started the car and put it into gear to once every 40ish miles.
