i have been having idle probs now for a few weeks with it stalling out all the time. I have just run the self diag checks the only fault ive got is 411 412 wich is base idle irregularity ( no s**t ) so i done the base idle check as per the book and according to my timing light the timing is about 10 deg out retarded now this would explane the idle problems but i cant fig why its done this. Now i have pulled off the rocker cover and manualy checked timing marks and the cam and crank pulley marks line.

SO PLEASE HELP SOMEONE.
