1990 Chevy Cheyenne Starter Replaced, now timing problems

So this truck sat for quite a while, so I would say it needs a bottle of heet but I doubt it......it needed a new starter though obviously cause it finally started. Also dont think the ignition switch rod was doing its job, so turning the switch off manually for now.


BUT NOW:

I am getting pinging/sputtering now in third and fourth gear, which is HAS to be a timing issue now because the faster I go, the more pinging/sputtering its doing.

I am going to double check my firing order for my spark plugs, and this is a fuel injected if that makes any difference. I did replace the distributor cap and the rotor, but that requires nothing special.
