was test driving the car, and i kept loosing the engine when i got my foot in it at every gear. checked the codes and got 12 13 34 & 45. 34 is cuz i removed the egr. i checked the waste gate and it is real hard to move by hand i didnt get a power loss light. question is about wg vac line there were none when i got the car so i made them. could i have screwed somthing up in making the line to the wg act?
