I still have the p0300 code but I ordered a new distributor and cap and rotor I'm going to install that today and see if it fixes it

@@matthew1er you will need a computer to set timing on it has to be between -2 0 +2 if try just the cap and bug off it first if that don’t fix it I’d do the distributor
