I am not certain that an extra quart of oil would give you the problems that you are asking about, but overfilling your crankcase does increase the pressure inside the crankcase and may force oil where it shouldn't be going. In particular, your EGR system might start sucking up much more oil vapor or even liquid oil and mixing it back into the fuel stream going into your engine. I have had carbureted vehicles with tired engines (i.e., a lot of blow-by and oil vapor in the head) where the plugs have fouled because I have drawn too much oil vapor into the fuel system--in those systems, the EGR valve fed back into the air box, so the air being drawn in to mix with gasoline was laden with a lot of oil vapor. That fouled the spark plugs quite nicely, and I'd have to change or at least clean the plugs after a while to keep the engine running properly.

I am less persuaded that excess oil vapor can plug your fuel injectors. The injectors are designed to squirt a precise amount of gasoline into the air that's being drawn into the engine. The "oily air" would never be on the high pressure side of the fuel injectors. I suppose it's possible that oil could be deposited on the outside of the fuel injector in such quantities that the injector wouldn't spray in a proper pattern, reducing engine performance. However, the fix for that would be pretty simple: remove the fuel injector and carefully clean the outside of the injector with a serious gum-cutter like Berkebile 2+2 (which is much more potent than standard carb cleaner). That fix would be both faster and cheaper than disassembling the injectors to clean their internal parts.

Slight rough idle in park warm or cold after warmed up a lot rougher at stop light but doesn't stall/ normal driving speed run great


seeing how the truck is an 88 there could be a few solutions that will not cost alot of money. I would try to add fuel injectior cleaner to your next full tank of gas as well has using a higher octane fuel or octane booster. Also try some heet. this takes some of the extra moisture out of the gas and should be added in a full tank as well. Some of the Lucas brand injector cleaner will remove moisture. If there is any knocking in the motor, on your next oil change put in a bottle of Lucas oil treatment or something I use called Hyper-Lube. They both are only 1 quart bottles so you will short the amout of oil put in the engine by 1 quart. When the truck is sitting overnight or for a few hours especially in a cool environment the oil will get thick, when the truck warms up the oil thins and you notice problems like what you described. I live in Indiana and the winter here can be a bit rough on a car/truck. If additives don't solve the problem then you will have to look into the possibility that there is a mechanical/electrical component that is bad. They can be:
throttle position sensor
dead fuel injector
lose of compression in a cylinder
dirty fuel filter
dirty air filter
spark plugs
engine timing off
faulty spark plug wire/ wire being on the wrong plug causing firing order being wrong
since it runs fine at driving speed I would check into the fuel injector cleaner 1st. The injector or the throttle position sensor.
I have a family member who has the same truck and for a smaller truck it's pretty tough. Definately a keeper
