Hi Guys,

Many thanks for the responses.

Here is an update I rechecked the repairs i had done on the MAF wiring and found a bad connection. Fixed this and it started on twelve but ran rough. Reset engine modules and it ran sweet, but right bank O2 was stuck at 900mv. As the fuel trims set it closed the inj pulse on this bank until it hardly ran at all. At least this gives me a fault to chase now.

But it gets worse

Unfortunately for me, I had the snappy on it at the time and had used this to graph the O2, being too lazy to look for the O2 plug or hook up the scope. Snappy froze when exiting the graph mode. I left it for the night and found a flat battery the following morning. Since this the alarm has been playing up. It will not dis-arm, the LED on the door will just flash red. If I disconnect the battery and reconnect it the LED will then flash green. While flashing it will hesitate when the key is flashed, but continue to flash. Wheather this is connected to the snappy freeze or not I dont know. I had to remove the snappy battery before it would boot up again but has worked fine since. I look after another 600 which has had battery problems before but never had any trouble with the alarm because of them.

So, when I get the alarm sorted I will chase the fueling fault and let you guys know how I get on,

Again, many thanks,

Alan
