Take your steering wheel off and clean the contacts.
Go and look at your hicas ecu and check all plugs

Did you ask them how much it would cost to buy the wreck? If your so set on keeping the car then buy it back take what you want, sell what you dont want and see how your life is.
Or just buy a pulsar until you're off your p's. My pulsar is still kicking and insurance companies never blinked twice in repairing it.
