Default 1984 2.3 Rough Idle. Video to show

Working on my '84 2.3 and its not running the greatest. Here in the video you can see its got a very rough idle. (i do not touch the throttle at all. You will notice when i Do rev it up) Also does the same thing when i let off the gas out driving around. And on acceleration at the lower end of the RPM's its a little rough running. But seems to clear out at the higher RPM's. So far i have done is ran the old gas near empty and filled with new gas and added sea foam. I also changed all for plugs. (Stock Originals.) Right now i got on order is a distributor cap/rotor kit and plug wires.

From the sounds of the engine in the video and my short description what else should i check into?

it could very likely be the cap and rotor, if they dont have good contact it will not fire on the cylinder... swap those out, make sure the plug wires are in the right spots, and let me know what happens

maybe check to see if its the intake gasket, but it could be something else just something to check tho. you can spray like carb cleaner around vaccuum lines or the intake and if it changes idle thats where it is. someone correct me if this is wrong

Well i think i did find the main problem. Intake gasket much be suckin air. I started her up and she was idling like in the video. Sprayed starter fluid down around there and rpms went up. So i will be getting a gasket now also.

Thanks guys so far!

MMm could be somthing in the carb itself, its easy enough just pull it off and blast the whole thing out.

Made a HUGE differece on my 83

Well after a little more playing around i begin to think its one of the gaskets on the bottom of the carb to the manifold.
