That means a hesitation in acceleration. There are lots of possibilities these happens when the car hesitate to move quickly.
Have a full tune up of your engine, just to clear up the possibility, air cleaner, fuel filter, sparkplugs, ignition timing, high tension wire( spark plug cable ), and cleaning up the airflometer.
Have your favorite mechanic do check on those first.
That hesitation have two major part that always breaks down, the fuel filter is already blocked and the ignition timing ( distributor igniting points corrosion and vacuum advance failure due to vacuum leaks ).
Hope that helps you.

HI MIKE MY NAME IS JOHN YOU HAVE DISCRIBED YOUR PROBLEM WELL SO I KNOW YOUR NOT A DUMMY SO LETS THINK ITS NOT SPARK FUEL OR AIR THEN IT HAS TO BE VACCUM NOT EGR TRANS VACCUM IS ALL THATS LEFT TRY TRANS MODULATOR ITS VAC OPPERATED I CAN'T SAY FOR SURE BUT IT SOUNDS LIKE IT I;LL GIVE YOU MY E MAIL I DON;T DO THIS FOR A LOT OF PEOPLE BUT YOU ASKED A GOOD QUESTION PIER.J@SBCGLOBAL.NET
The timing marks are not properly aligned or the distributor is not aligned properly.
You'll need to get a service manual for the exact settings, make sure that after you set the marks you rotate the engne 2 complete revolutions & recheck the marks prior to reassembling the covers. Double check the distributor timing as well & check for any possible vacuum leaks from hoses or gasket problems.
If your chain had broken originally, then you possibly have some upper engine valve damage that will have to be diagnosed. A compression test will reveal any bent or broken valves.
Could be a few things. IS the check engine on? Could just be a bad mass air flow sensor. Or a seized wastegate. Yuo can start by trying to unplug the mass air flow sensor. If it runs better it could be just that. Just make sure to remove and clean the lower air filter box change the air filter and the snow screen which is located next to the battery where the air enters. These always are blocked. If it runs ok (not perfect change the mass air flow.
The two most likly causes of your Idle problen are, low fuel pressure. try installing a new fuel filter. Or the other one is the Air Idle control valve, can cause the exact problem you discribed with a cold engine. Fuel Injection engines do not have a choke like carburated engines do. So the idle is computer controled thru the Air idle control valve.
