i fixed it for sure .i had replaced the idle control box little green one when i first started having this problem .but all simtoms still lead to this little green box so just for the hell of it i took the one out of the 733i we just got and sure shit the think idles perfect no surge with lights or blower all this time and it was two bad idle control boxes i guess three is a charm !!! car runs so nice thank god i dint give up on the thing thanks for all the responses im going for a drive
