hey guys --- soooo, I need some help....I picked up an 01 530 on the cheap cheap...cheap --- nice car! So it runs like crap, missing like crazy. Had 12 codes, so I cleared them all, checked the coils and plugs. Coils looked ok, plugs looked like crap. But in new plugs. Cleared codes...it ran better but still crappy. Had misfires on 4, 5, and 6. Swapped coils in 1, 2, and 3, to 4, 5, and 6. Cleared codes and restarted, came back up misses on 4, 5, and 6. So, Im assuming my coils and plugs are good. Then I heard the DISA valve....yup....broken and it was sucking air. So, I went out and bought the gasket I discovered to reseal the DISA valve but the flapper was broken so I yanked it out. Reinstalled everything and it still runs like crap, and was cutting off. I blocked air flow at the MAF and it fell in it's face so I know it is not getting air from anywhere. After clearing codes and running it again it tripped P1351 0171 1349, which 4 and 5 misfires, and also a lean code.
So........the only thing I can see is the flapper on the DISA -- I sprayed down everything with brake clean and nothing changed. Checked for vacuum hoses, checked intake boots...I cant see anything cracked or pulling excess air.
I guess maybe the injectors could be bad but I doubt. I am thinking about taking the DISA out of my 330 but I REALLY dont want to.
I did some research on if our cars NEED the flapper..some say yes, some say no....so....I put it to you!
