I have a DD, with a 305. the dang thing never wants to idle at stop lights...its an electronics problem i can't seem to figure out-all the sensors and crap are now NEW. (wasn't throwing any codes) I disconnect the wire to set timing-and it idles great( idrove it disconnected-great except when i get the RPMs a lil high it doesn't advance, so sputters)...connected cough sputter sputter...die. I am lead to believe its a timing issue, but the computer is leaning it out i think. I am thinking of eliminating the computer altogether and going carb. Someone posted info on a 300HP+ 305 building the top end only, and its very tempting, and that set up had a carb.....any thoughts on this??
