I was looking at my EGR Tube (the accordion pipe from the pass ex manifold) and I noticed that the temperature sensor is no where to be found. Where does this plug into? It comes off the Egr tube and plugs into...? Also, I have a small leak from this tube, does this cause the engine to either miss at idle or stall when put into gear? Also do you guys know of any remedies to fix a crack in the accordion part of the pipe? jb weld?...
