Paul1979 I changed my manifold today due it was crack and fitted the remus center pipe as well but i have a problem my orange light is staying on i have disconnect my battery as well to reset my ecu but the light is still showing up any ideas? Paul
philip1 make sure all the O2 sensors are plugged in. some times even if it looks OK it might not be in properly. also you may have a failure elsewhere that caused the mani to crack. perhaps AIT sensor has gone bad or the coolant sensor both of those affect the mixture and being out of spec could run you lean overheating the mani causing the crack.
vocky leave the battery off for about 10 minutes, if it's still on take it for a slow drive, it may go out but as said above, could be a loose wire somewhere otherwise it's tech2 to find the error code
