I just remove the negative battery lead from the battery, leave it off for a while, pump the brake pedal, turn all the lights and stuff on and off, then wait some more, go have a coffee, then come back, put it back on.
Start car, let it idle for five minutes, then go have a drive.
Seems to work for me.
BASS OUT.
PS. Do the hicas diagnostics thing. You will laugh your arse off at the back end of your car dancing!! Remember to do it with the front wheels pointing straight ahead though!
