chrisvr6t 19 Posted July 27, 2014 Report Share Posted July 27, 2014 Hi people been a while as my last engine decided to cap it's bearings out and seize up on the Dyno and low compression in cylinder 3 but still made over 330hp lol.Right my problem I have is when the car gets up to temp it will start to misfire badly and eventually cut out and won't start again till cooled down! I've been checking the obvious like fuel pump relay and noticed that they get red hot like piping hot once relay has cooled down it will fire back up like normal I've tried a number of relays and same thing! So I have come to a conclusion that the fuse box maybe faulty in some way, what else can I check? I've changed the sensors on the water housing, just to clarify this a obd2 vr6 with 630cc injectors UM software.. Any help is appreciated Sent from my iPhone using Tapatalk Link to post Share on other sites

dom.joy 87 Posted July 29, 2014 Report Share Posted July 29, 2014 Checked for a cracked coil pack. Caused mine to misfire real bad and only when hot. Never cut out though. Link to post Share on other sites
