MAJOR help needed
After christmas.. installed my catback exhaust.. then put in a greddy type rs bov... reset the ecu after installing both.. drove the car and the bov fluttered and then when the clutch was pushed in the car would drop in rpms to like 100 ..and sometimes make the car died.. found out that the greddy flutters whether you want it to.. took the greddy out and put the stock POS back in... it also fluttered and drops in rpm but not as low as the greddy did.. maybe to 400.. most evo 8 owners upgrade there plastic pos bov to a evo 9 bov.. i did so.. came today.. installed the evo 9 bov.. on a side note.. i notice the vacumm line was a little short so i put a longer line on.. after resetting the ecu.. drove the car.. IT FLUTTERS.. and its also drops in rpm to 100-200.. what is the deal.. i tried searching but couldnt find anyone with the same problem as me...
i tried the mr bov with the original vac line.. it stil fluttered... so i made the change of making it longer to see if that was the problem.. still fluttered and kills the car
Are you getting any check lights? I think I read somewhere that a DV can flutter because it doesn't have enough vacuum to open correctly. Maybe you have a vacuum leak somewhere on the manifold.
How is the car running overall? I had the vacuum line at the left end of the manifold come off and it had the same issues your describing with the low rpm drops, but I pulled over and put the line back on, never boosted to know what the DV was doing.
