Hi
i have a gc8 which i cant get to idle properly no more have replaced the air flow sensor an knock sensor as this what computer said. car runs better now but when it comes to idle it seat at normal revs than dies n either stalls or runs badly and have to keep reving it, than when take of it breaks down but once driving all is good car runs good.
also has a pod filter n front mount no other mods, car was running good for a year since had it now i dont know .
any ideas to help out as there are many modified gc8 out there
