1994 Subaru Legacy, twin turbo, BD4, EJ20. when driving the car
specially when rpm pass 3000, the car just like cut off many times,
when reduce the speed, goes fine, check engine on, scanned and found
code 66 which is Twin Turbo System.
Check the system and found a vacum hose torn. Replaced this hose and
car stopped doing the cut off but check engine still on. Reset the
memory by scanner, but check engine return back again. scanned again
and found code 66. Turbo system seems work fine. any idea?
thanks
