ok so i got my 95 5.0 about a month or so ago, was not running replaced distributor and got it to run not well but it ran(shook alot), but was not timed correctly at all. so tonight i got it set right, triple checked all the wires. there all correct. i brought it up to tdc. took dizzy out set rotor to number one cylinder plug. witch is facing the intake manifold.the 0 degree mark lined up with the pointer.. took the pill out. marked 10 btdc, fired it up set it to 10 btdc started missing than put pill back in and it got even worse. if i retard the timing it clears up. i also replace plugs and wires so i know there all good. i re did the timing set up 3 times and came up with same results . i am at a complete loss here. can anyone give me ideas. i feel its something dumb. just cant figure it out. thanks people for your time.
