hey all

I have a 87/88 305 tpui motor with the cpu that came with the car/motor. My first question is dose the vss senors have anything to do with the motor running( driving down the road)? Mine is not hooked up ,there is an cable speedo hook up now ,I have the senor that came out of it ,but it did not have any place to plug the vss into it .I thought it was just for a electric speedo ,it had a eletric speedo with the car not hooked up and having no info on it i chosse to do any with it .
Also I was reading alot of posts on different things here,so it brings up many questions. I have what I think is a timing issue, when step on it from a stop its spits spudders and back fires until I let up and ease into the gas but if im already up to speed in can step on it and she just gose!!! This is only a problem when im driving ,in the garage in park there is no problem,so thats what lead me to the vss not being hooked up ,but ive been told it sounds like timing
Where should the mark be ??? dead center of the scale ,advanced ,retarted???
Mine is about dead center of the scale
I guesss Ive rambled enough for now,and info ,advice will be great
thanks all
Jeff
