Howzit ST members! I've been having this engine light problem for about 4 months (P0172/P0175) on a 2nd generation ST 4.6L 2wd. We've gone through new injectors and replaced them. A diagnostic check from the dealership. They said exhaust manifold leak and MAF sensor. A significant exhaust leak with broken studs fixed. A new MAF sensor replaced. We've been trying everything. We looked at the plugs they were clean no signs of rich conditions. The computer was referring to a negative 20 fuel trim. I read in some old posts about the infamous cracked elbow. Could this happen with the 2nd gen ST. Where is this elbow located (pictures would help alot). Any other information will be appreciated too. Thanks in advanced Kyle
