Hi guys, I've been having a problem with my 2006 350z import for a few months, my tdc off and slip light came on whilst driving, my revs also dropped to 0 and my air on fan was on, had a little fiddle and it turned off but every 2 days or so if kept happening so I would just turning the car off and on several times whilst rolling and seemed to turn off, the last 5 days it has happened twice but this time when this problem occurred my car won't turn back on? I tapped the side of the panel in footwell where I believe the ecu is and locked and unlocked the car and it seems to turn itself off and car will start again? Any suggestions?
