Was it doing this before you changed them? something is wrong with your firing, recheck firing order. could be a component you swapped in is faulty. if it was doing this before you changed them check crank sensor and lambda sensor

    lambda sensors are attached on the exhaust system and measure exhaust gasses they have a direct bearing on how the ecu will demand fuel.. crank sensor will have a direct bearing on timing. I'm afraid i have never used a multimeter to test them. Its one of those faults that could have many causes. check integrity of vacuum pipes, inlet hoses/ducts. clean out the throttle body.

SOURCE: My 1986 Nissan 300zx non-turbo was running fine,

It sounds like the number 2 injector is hung open.

It will dump fuel and cause all sorts off issues with the ECU.

You should ohm that injector and compare it with the others to see if it is wildly different. If so, change it out and retest.

I would check your intake gasket. Get your self ome carb cleaner in a spray form/can and perfrom this test. Run the car and spray the carb cleaner on your intake gasket which is right by your injectors. So pretty nuch spray it at the injector rail and listen fot change in idle, If the idle changes, the intake gasket is torn and you are running lean, because of a vaccum leak. Common problem on your model car. Perform test and let me know what you find.

Why would a 1995 Nissan pathfinder v6 idle roughly in general idle mode?


Although usually fuel problems are actually electrical problems, check for a vacuum leak, hissing around the intake manifolds, and the acknowledged test is to carry out aimed squirts of WD40 at the joins in the manifold and see if the revs rise or fall.
after that check the idle air control and the Mass airflow sensor, and definitely clean the MAF if you haven't done so recently...

1996 Audi A4 2.6E - Not idling properly.


The ignition coils on your Audi A4 are what provide the spark to the spark plugs, which sit underneath each coil. Every cylinder in your A4's engine has a spark plug and an ignition coil assigned to it. Sometimes, the ignition coils can fail and require replacement. Typical symptoms of a failed ignition coil include a flashing "Check engine" light, a rough idle or hesitant acceleration. Replacing the ignition coils on your A4 is a quick procedure that takes just a few minutes.


Instructions
    • 1

      Park your Audi A4 on a level surface and open the hood.

    • 2

      Remove the plastic rivets that secure the plastic engine cover to your engine with the flathead screwdriver. Depending on your engine, there may be either three or four plastic rivets, which are all very obviously placed. Set the engine cover aside.

      • 3

        Firmly pull the ignition coil you need to replace up from the engine. Since it does attach to the spark plug, you will need to apply a little force. Be sure to pull directly up so that you do not bend the metal rods at the bottom of the ignition coil.

      • 4

        Unplug the ignition coil from its wiring harness. Depending on your engine, you may need to use a flathead screwdriver to pry up the loosening latch on the wiring harness.

      • 5

        Insert the replacement ignition coil into the spark plug cylinder and push directly down until you hear a slight popping noise, which will indicate that it has been installed correctly.

      • 6

        Replace the plastic engine cover and secure it with the flathead screwdriver and the plastic rivets to complete the procedure.

    P1320 runs smooth no misfire


    These engines had a lot of problems with coils, most people just end up replacing all of them. You may find them a little cheaper online. There was a bulletin for broken or worn wiring inside the harnesses that go to the coils so you should carefully check back along the harness to each on, especially where the harness might move when the engine torques over.
