Hi
I have a 1996 wrx import, it has a Z5 ecu and I have now fitted a 3"after market exhaust system and up pipe and down pipe, problem is I have found engine will not run with down stream o2 sensor disconnected, runs for a few seconds then cuts out and will not run again, any body got any ideas why ??
