was the alternator changed it and i ran great no misses or anything i also cheaked the wiring andit had a crack in it but i fixed it prior to the problem wif my alternator, as for the regulator mine was external and it took me a while to figure out why my new alternator was'nt charging, it was due to it having a built in regulator so having two was a real problem so thats one thing to check if your changing you alternator after that was done the z lives
thanks for all you help cheers pauly
