Re: 1986 monte carlo (4.3) Sign In

duh,sorry ,just reread your post,see wires were replaced.....you know i've had this before and i'm drawing a blank...i'm assuming all parts replaced were new......reminds me of the german army during world war 2.
the commandant came in to the barracks and told the troops that they had to "change underwear today".
then told them that hans had to change with franz, wilhelm had to change with helmut,etc...lol....sorry...ok,back to the problem....i know that spark will take the easiest path.....have seen spark ground out thru the bottom of the rotor to the distr.shaft...but since all is new,only thing i can think of is the module...
