1993 galant rough idle

[Julio_1G]

I have a 1993 galant 4g63 sohc and i have a problem with it at idle. Though the rpm stays steady you still feel almost like a small misfire and it feels like its chocking itself until it goes above 1500rpm and smooths out. Ive done a compression test and it came back good with cylinders reading 185-190. recently i changed 2 fuel injectors because they were clogged and am wondering if i should change the other 2 also to see if it would help. things ive changed: distributor, plugs, wires, fuelp pump but that was because it sat for like 6 months because it wouldnt start.

**UPDATE**
i decided to go ahead and replace all 4 injectors which solved my idling issue. now the only problem left is a rough cold start to where it feels like its choking itself for like 2-3 seconds and then goes away. Only happens after cold starts when the car has been sitting for a couple of hours.
