i have a 97 m3 with ERT supercharger 6psi bought the kit used off ebay, when i brought the car out of storage i decided to install m50 manifold on it and now when the car sits over night or engine cools off completly i won't start it takes few tryes and then will fire up no problem. Does anyone know what the reason for this would be?? i got a vacum leak?
btw car is turning over but it won't fire up
the other thing is when the car is idleing i got about 10-11 psi of vacum on my boost gauge does anyone know what it should be?
