Which cylinders are missing? The pressure regulator is on the passenger side (cyl 2 4 6 8 ) and if blown will leak raw fuel into the engine. What parts did you use in the tune up? Just because the balance test came out ok doesnt mean the injectors are spraying a good patter or the exact same amount. HAs a compression test and leak down test been done to verify the engine is solid and doesnt have a leaking intake valve or two
