1994 Toyota Tercel 4 cyl Front Wheel Drive Automatic

when the car is stopped but still in drive(like at a red light), it has a tendency to shimmy and shake very roughly and sometimes stall out. Spark plugs and wires have just been replaced so they are brand new. Do you have any advice as to what may be causing this?
thanks

You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs! If that doesnt do it, you may need a new idle air control valve, it's bolted to the throttlebody
