I think I have stuffed the ecu on my EF XR6. Jumpstarting without proper efi jumper leads. It surges when idling, cooling fans come on when I start the car on a cold morning, trans econ/power mode light blinks, trans goes into final overdrive at 55kmhr-1100rpm.
Anyone know if there are alternatives to tested second hand ecu's or new ford ones? Any answers before I book with auto elec and he tries to overcharge me.
